Detailed explanation-1: -Bases can be defined as substances which when dissoved in water produce hydroxide ions(OH-).
Detailed explanation-2: -Soluble bases are called ALKALI. pH is a measure of the hydrogen ion concentration in a solution. An acid will dissociate in water producing hydrogen ions.ie: releases H + ions in solution. A base (usually containing a metal) will dissociate in water to produce hydroxide ions.
Detailed explanation-3: -Bases can be defined as substances that produce hydroxide ions when dissolved in water (OH–). Acids and bases. An Arrhenius acid is any substance that ionizes when it dissolves in water to give the H+ or hydrogen. An Arrhenius base is any substance that gives the OH–, or hydroxide, an ion when it dissolves in water.
Detailed explanation-4: -Bases are substances that neutralise acids and if dissolved in water, turn red litmus blue. When an acid and a base are combined, water and a salt are formed. For example, when hydrochloric acid is mixed with sodium hydroxide, water and sodium chloride are formed.
Detailed explanation-5: -A base is a substance that will dissolve in water to yield hydroxide ions, OH−.
