The process of carrying out a titration allows us to accurately measure the volumes of an acid and an alkali required for neutralisation. An indicator will be used to determine the exact volume ...

The pH of acidic, basic, and neutral aqueous solutions of salts is shown with ammonium chloride, sodium acetate, and sodium chloride. Place beakers containing distilled water and universal indicator ...

An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

THE structure of polyadenylic acid can be expected to have some influence on the availability of polar groups, such as the primary amino-group of the adenine base, for binding of hydrogen ions.

UNDER this title McHenry and Graham 1 have published an investigation on the ascorbic acid content of raw and cooked foodstuffs. They found in the case of cauliflowers, carrots, parsnips, beets and ...
