Bases increase the concentration of hydronium ions by donating hydroxide ions to water molecules is False.
<u>Explanation:</u>
Bases are counterparts of acids. They take Hydronium protons from water, and increase the OH- I ions in the solution. One example for this could be ammonia.
When ammonia is added to a solution it accepts a proton of hydronium and becomes ammonium ion.
Solutions which posses’ higher concentrations of hydronium are called acidic solutions and those possessing lower concentrations of hydronium ions are basic in character. Also, pure water is neither acidic nor basic; therefore the concentration of hydronium ions in pure water is neutral.
Answer:
option A
Explanation:
The correct answer is option A
