Answer:
D - Hydroxide Ion (OH-)
Explanation:
A base provides either hydroxide ions (OH–) or other negatively charged ions that combine with hydrogen ions, reducing their concentration in the solution and thereby raising the pH. In cases where the base releases hydroxide ions, these ions bind to free hydrogen ions, generating new water molecules.
(3) both a chemical and a physical change can reach equilibrium. For example, an acid-base reaction can achieve equilibrium (chemical change), and a system can achieve dynamic equilibrium (phase changes from liquid to gas, for example), which is a physical change.
