Hydronium ions are formed when an acid donates proton(s) to water molecules. They are represented as H3O+.
These are negatively charged particles formed when a base donates electrons to water molecules.
A solution with a higher concentration of hydronium ions than hydroxide ions.
pH Value: The pH value is used to measure the acidity or basicity of an aqueous solution. It's determined by the concentration of hydronium ions in the solution.
