This then leads to the fact that the partial negative and positive parts of the water molecule can break the bonds of ionic and polar molecules which causes them to dissolve within the…
6.What are the various parts of a solution? There is the solvent which has the greatest abundance and there is the solute which is what is being dissolved. 7.Distinguish between an unsaturated, saturated, and supersaturated solution. Saturated is when it does dissolve in the solvent, supersaturated is when the solute does not dissolve in the solvent and unsaturated is when some of the solute dissolves in the solvent.…
surface area vs rate of time Introduction: In the investigation an experiment is conducted investigate if the breaking of alka seltzer into ½, ¼ and none effect the time it dissolves. The context of the problem is the time it dissolves to have the medicine show its effect. This problem exist in real life as people take alka seltzer to relief heartburn, acid digestion and stomach aches.…
A solution is a homogeneous mixture of elements that are dissolved in water making it an aqueous solution. Solutions can form an acid, which is a substance that dissolves in water and gives a hydrogen ion, or proton (H+), to the water. It can also form a base, which is a substance that dissolves in water and…
Diffusion Hello today we will be talking about a skittle sure a skittle is delicious but did you know it could be used for many more than just eat. Did you know that you can make an experiment with just a skittle and some water well that’s exactly what we did got a petri dish and filled it up with water then we put the skittle in the middle of the dish. As soon as we placed the skittle in the water it stated dissolving and the water turned orange the skittle got tiny and the top of the skittle got rough.…
No one ever expected for sugar sweetened beverages to become a threat to human health. The article Ounces of Prevention-The Public Policy Case for Taxes on Sugared Beverages is a depiction of the growing worries of experts in public health; Kelly D. Brownell and Thomas R. Frieden manifest the importance of increasing the taxes on sugar sweetened beverages in order to generate a decrease in consumption, promoting people to make a wise selection to reduce the rate of obesity. The ascending consumption of sugar sweetened beverages is presented as the “largest driver of the obesity epidemic”. Imposing an excise tax may be a solution to this preventable problem. Demanding taxation on sugar sweetened beverages will produce a revenue.…
The Freezing point of water is 32° fahrenheit, But does anything affect the freezing point of water? The effect of salt and sugar lowering water’s freezing point is called Freezing Point Depression(FPD). When water freezes, its molecules slow down and “stick” together, and eventually slow down so much they stay in place and become a solid. However when salt or sugar is added, it “interferes with the formation of the crystalline bonds between water molecules that give ice its solidity”, Written by the Editors at infoplease in the article “Does sugar affect the freezing of water? Why?”.…
Finding how could a substance’s ability to dissolve effects by the temperature of water using ammonium chloride, which is a solid that has high solubility in water. Solubility is the ability for a substances, the solute, to dissolve in a solvent. Solute is the substance dissolved in the solvent, and solvent is the substance that is dissolving the solute. So the solute will be ammonium chloride and solvent will be the water. Solution is what they created after the solute dissolved in solvent.…
Water boils because the high temperature of the stove-top makes the liquid's temperature increase, in which makes it bubble. To start off, the water molecules are constantly moving around; by the virtue of the calefaction, which means heat, or to be heated. Heat is a lot like pressure to atoms in the water. When warmth hits the iota, which means small particle in the water. The iota gets crushed down into a smaller version of itself, which makes the water boil.…
Discussion Graph 1 displays the reaction time (in minutes) of how long it took for the Alka-Seltzer tablet to completely dissolve per trial. Graph 2 displays the averages of the reaction time which showed the higher the water temperature is, the faster the reaction time would be. At 65⁰C the average time for the Alka-Seltzer to completely dissolve was 1 minute 4 seconds followed by 1 minute 20 seconds at 35⁰C and ending with the highest average at 2 minutes 1 second (1.61). The hypothesis stated that hot water temperature would make the Alka-Seltzer tablet dissolve the fastest.…
The theoretical concepts that underlie the Hot Ice experiment involve a supercooled, supersaturated aqueous solution becoming a solid. When a liquid is cooled beyond its freezing point but remains liquid is known as supercooling or undercooling, and being supersaturated occurs when the solutes in a solution exceed the saturation point. The sodium acetate in a supercooled state will rapidly change into a solid with the addition of physical energy or a nucleation site. During the transformation of the liquid supercooled solution into solid crystalline formation produces heat in an exothermic reaction, hence the name hot ice.…
Investigative Question Does sugar or salt effect the freezing point and period of time that water takes to freeze? Hypothesis If you add either sugar or salt to water it will affect the freezing point of the water and will therefor take longer to freeze. Aim…
The Thermodynamics of Potassium Nitrate Dissolving in Water Introduction: This experiment focuses on thermodynamics or the study of heat and molecular randomness. It helps illustrate how and why potassium nitrate (KNO3) dissolves in water. When it dissolves, it dissociates into potassium (K+) and nitrate (NO3-) ions. These ions can also recombine into solid potassium nitrate. This reaction can reach a state where concentrations of ions remain constant or Ksp; which stands for the equilibrium concentration for the solubility product.…
The process that produces soap usually from the base hydrolysis of a fat or oil is called saponification. It is also known as soap making. Formerly, it is the reaction between an ester and sodium hydroxide to yield sodium stearate. The beef was used as triglyceride by boiling it with lye or an impure sodium hydroxide. The top layer is the sodium stearate wherein once it was cooled and turned into solid it was chopped into cubes of yellow soap.…
Cyclodextrins are enzymatically modified starches composed of glycopynanose units which form a ring of either six (α-cyclodextrin), seven (β-cyclodextrin) or eight (γ-cyclodextrins) units.
