NURSING ANM AND GNM

Detailed explanation-1: -Base: A solution that has an excess of OH-ions. Another word for base is alkali.

Detailed explanation-2: -Addition of an excess base to a solution of sodium hydroxide means an addition of more hydroxide ions (OH−). This will increase the concentration of hydroxide ions (OH−).

Detailed explanation-3: -Answer and Explanation: A substance the dissolves in water and produces hydroxide ions is a base. While most bases like potassium hydroxide and sodium hydroxide contain the hydroxide ion itself (KOH, NaOH), others like ammonia (NH3 N H 3 will form hydroxide ions when dissolved in water.

Detailed explanation-4: -A high pOH value means a low concentration of hydroxide ions and therefore an acidic solution. A low pOH value means a high concentration of hydroxide ions and therefore a basic solution. Coffee, with a pH of 5 and a pOH of 9, is mildly acidic. A drain cleaner, with a pH of 14 and a pOH of 0, is extremely basic.

Detailed explanation-5: -Therefore, the concentration of hydroxide ions increases per unit volume, when excess base is dissolved in a solution of Sodium hydroxide.
