|
What is an acid?
|
An acid is a chemical compound that dissociates in solution, releasing hydrogen ions and lowering the solution pH (a proton donor). An acidic solution has a pH < 7.
|
|
|
What is a base?
|
A base is aqueous substance that can accept hydronium ions. Bases are also the oxides or hydroxides of metals. A soluble base is also often referred to as an alkali if hydroxide ions (OH−) are involved.
