1. Locomotion. This does not occur to any appreciable extent in distilled water, acids, bases, KCN, H2O2, the leucobase of methylene blue, sugar, alcohol, papaverine hydrochloride and quinine (the alkaloid, not its salt), when Amoebae are immersed in solutions of them in the concentrations mentioned. It does occur for varying lengths of time in certain concentrations of all the neutral salts
Prepare a baking soda solution by dissolving about a teaspoon full of baking soda (NaHCO 3) into 50 mL of distilled water. Take the pH of the solution and record. Divide the solution into two portions. To one portion, add 2 drops of 1M HCl and swirl to mix. To the

Aniline is a basic compound due to the presence of lone pair of electrons on the nitrogen atom and hence it reacts with hydrochloric acid to form phenyl ammonium chloride and becomes soluble in HCl. Then it is diluted with distilled water and the
distilled water, hydrochloric acid (1 N, HCl, Alfa Aesar, USA), and NMP were mixed at a volume ratio of 5 : 1 : 0.02 : 3. The NMP was added after the reaction of silica sol to prohibit phase separation between the PEI solution and silica sol during the preparation
Brief Description: A solution of milk of magnesia and universal indior in water is stirred while acetic acid is added. The indior changes color as the acid is neutralized. As the suspended solid is consumed, the solution becomes clear. Purpose/Goal: Procedure
