Ion

the ions with the same charges, lineup, repel, and split apart. Ionic compounds cannot conduct electricity as a solid because they don’t have mobile particles. Due to the fact it’s a solid, the particles are stuck together, shaking in place and don’t have the ability to move in one general direction. The ions are unable to come into contact with the electrodes of the probe. Ionic compounds are soluble in water. The H20 breaks apart the ions, the H20 goes between the ions, and the H20 and ions…

completion of CEM 161 Section 009, under supervision of Abstract: In order to determine the identity of the compound we performed many experiments with a solution of the compound. These experiments included testing for all of the following ions; ammonium, halide, sulfate, carbonate, nitrate, and acetate. After comparing the results of these experiments we determined that our compound contained a halide. By using the flame test with a Bunsen Burner we also determined that our compound…

The stories Conducting Solutions, Energy Story, and the video Hands-On Science with Squishy Circuits have all helped me learn a lot more about electricity. The purpose of these sources were to help the reader to understand and inform the reader about how electricity is made. It also showed how easy it is to make electricity. These three sources have many differences and similarities but they all serve the same purpose. In the video Hands-On Science with Squishy Circuits it talks about how easy…

raised depends on how much of the solute there is. This makes the water dilute which means that most of the water molecules are at the bottom and few can escape. This is known as reducing vapor pressure of water. Table salt breaks into a sodium ion and chloride ion, so there are two particles. Sucrose would remain as one particle. (Your Mother Was a Chemist. (n.d.). Retrieved from http://kitchenscience.sci-toys.com/boiling_freezing_pressure). The question that this research helps answer is that…

between the cells. This is only restricted by any interactions with the cell membranes lining this pathway. The symplastic pathway utilizes ionic channels and protein pumps [15]. For cellular uptake of strontium and calcium, cells may use non-specific ion pumps or element specific channels that only remove strontium and calcium from the nutrient…

results for the sulfate test due to the formation of a white precipitate, indicating the presence of a sulfate ion. For the sulfate test the unknown solution, potassium sulfate, and combining it with hydrochloric acid and barium chloride. If a sulfate anion was present in the unknown solution, then the anion would combine with the barium and form the precipitate, BaSO4, and the chlorine ion would combine with the unknown’s cation. In this case a sulfate anion was present in the unknown so the…

Solid solubility is whether that solid can dissolve in specific solvent or not. When a solid dissolve, the ions that comprise the solid will disperse in the solvent thus create a different concentration distribution within the solvent solution. Thus we can view this as a flow of ion from high concentration to low concentration (there’s a flow of ions) Electrical activity is the ability for electron to travel within the material. Specific solid material molecule will have free electrons to…

Overall the experiment provided significant data, despite problems with reagent contamination. Iron (III)-thiocyanate complexes in equilibrium, meaning that external and internal forces on the equilibrium can shift toward the reactants or the complex. External forces are changes to the chemical or physical environment that effect the equilibrium. Internal forces are changes to the bonds or chemical nature of the complex itself. These effects are used to study the optimal chromogenic reagent,…

covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. It only happens between non-metal atoms. Ionic bonding involves the electrostatic attraction between oppositely charged ions, and is the primary interaction occurring in ionic compounds.Atoms turn into ions when they lose or gain electrons. Since the atoms are particles in the matter,…

Covalent bonding occurs when atoms share pairs of electrons. Atoms will covalently bond with other atoms in order to gain more stability, which are gained by forming a full electron shell. By sharing their outer most valence electrons, atoms can fill up their outer electron shell and gain stability (Chem wiki) Nonmetals will readily form covalent bonds with other nonmetals in order to obtain stability, and can form anywhere between one to three covalent bonds with other nonmetals depending on…
