A)electrolyte.
B)salt.
C)cation.
D)colloid.
E)buffer.

Question

Quizplus · Accepted Answer

A buffer is a chemical compound that helps maintain a specific pH by either accepting excess hydrogen ions or donating hydrogen ions to the solution. Buffers are important in biological systems to maintain pH stability, which is necessary for optimal function and enzymatic activity. A) Electrolytes are substances that dissociate into ions when dissolved in water. B) Salts are a type of electrolyte composed of a cation and an anion. C) Cations are positively charged ions. D) Colloids are mixtures in which particles are dispersed throughout a liquid or gas but are too large to dissolve.
