Detailed explanation-1: -An acidic solution has a high concentration of hydrogen ions (H +start superscript, plus, end superscript), greater than that of pure water.
Detailed explanation-2: -Hydroxide and Hydrogen Ions This equation shows that the more hydrogen ions a solution has, the fewer hydroxide ions it must have. So: an acidic solution that has a large amount of H+ will have very little OH–. And a basic solution that has very little H+ will have more OH–.
Detailed explanation-3: -A solution having free/excess hydrogen ions is called an acid. A solution having free/excess hydroxide ions is called a base. So according to the above definition, clearly acids have more free hydrogen ions. pH of a solution gives the measure of the acidity or alkalinity of that solution on a logarithmic scale.
Detailed explanation-4: -1 (a) In aqueous (watery) solution, an acid dissociates into hydrogen ions (H+) and anions. Every molecule of a strong acid dissociates, producing a high concentration of H+.
