In this experiment, the goal was to figure out which solute would be the best at neutralizing stomach acid the quickest. As baking soda was added to stomach acid, then the time for neutralization was the quickest. From the data chart, baking soda had the largest average pH of 6.6. On the graph, it show how baking soda had the highest peak and how it was the closest to reach 7 than any other substance. The hypothesis is supported because baking soda was the antacid that was closest to…

Alkalinity is a measure of the ability of a water to resist changes in pH. Alkalinity in water is due to the presence of weak acid systems that consume by hydrogen ion produced by other reactions, allowing chemical or biological activities to take place within a water without changing the pH (1). In this way the alkalinity protects aquatic life. The measured value may vary considerably with the end-point pH used. Alkalinity is a measure of an aggregate property of water and can be interpreted…

Twenty kids one answer, who will figure it out. Everyone has been given the task to find the mystery mixture. At first they all had different clams. But now it is getting narrowed down. But there are some people that had different opinions. Everyone have been given water, a well tray, and a vial, along with other chemicals. I will explain how the class had gotten answer they did. And how they think it is right. The claim that will be explaining will be citric acid and baking soda. One of the…

when I mixed solid sodium carbonate with hydrochloric acid, copper (II) sulphate solution with liquid sodium carbonate, and during the end of the change when I applied heat to sugar. The test of mixing sodium carbonate with hydrochloric acid was a chemical change because of a creation of gas and the state of the sodium carbonate changing during the process, meaning a chemical reaction must’ve took place. Afterwards, the examination of mixing copper sulphate solution with sodium carbonate was…

“With increasing degree of calcification, the concentration of NaOH increases. The relationship between the concentration of NaOH and the factors in the calcified red mud liquor is given by three Equations (16–18): N_NaOH=1.29(N_1 m_1-N_2 (m_2-N_NaOH/1.29) (16) m2 = m1+m1N3 (17) r = 1000/m2…

1-Paper 2-gallon size Zip- Loc bag 3-Iodine beads (available from forensic supply companies) Note: Iodine crystals can be used along with a small amount of powdered vermiculite. 4-Rubber or plastic gloves are recommended 5-Safety glasses or goggles Safety Precautions Firstly,Wear safety glasses or goggles to protect our eyes from iodine vapors. Iodine is very toxic in nature , both as vapor and through excessive skin contact. Work in a well ventilated area is necessary. We must Keep all…

Using qualitative analysis, two cations in an unknown solution was identified. After repeated mixing, centrifugation, and decanting, lead was confirmed in Part A and barium in Part B. In Part C, different colored flames of metal species were observed using cation flame tests. Formula unit, total ionic, and net ionic equations were then composed for the identified cations. If the experiment were to be repeated, step 13 could be ommitted as barium was already confirmed in step 12 with the…

The different chemicals that were used in this experiment were Pilocarpine, Atropine Sulfate, Epinephrine, Digitals, Potassium, Sodium, and calcium ion concertation. Pilocarpine stimulates the effect of parasympathetic nerve stimulation by enhancing acetylcholine release. Atropine Sulfate is a drug that blocks the effect of the neurotransmitter acetylcholine which is liberated by the parasympathetic nerve endings. Cardiac muscle and skeletal muscle are both different in functionally and in fine…

vitamin c, phenolphthalein, methyl orange, deionized water and the following chemicals: sodium hydroxide, potassium hydrogen phthalate, hydrochloric acid and sodium bicarbonate. When it comes to these chemicals, make sure to wear the general protective personal equipment and handle with caution because these chemicals can burn. (MSDS Solution Center) For week one, the students first had to prepare the sodium hydroxide and the hydrochloric acid. Both of these were done by taking a graduated…
