Question

explain the term 'ionic product of water ' and 'pH value '. how does the former change with temprature?

Answer 1

 The product of concentrations of H+ and OH- ions inwater at a particular temperature is known as ionic product of water.
The total pH scale ranges from 1 to 14, with 7 considered to be neutral. A pHless than 7 is said to be acidic and solutions with a pH greater than 7 are basic or alkaline. Our ideal pH isslightly alkaline - 7.30 to 7.45

Answer 2

Water breaks down into hydrogen and hydroxyl ions.

• The product of the concentrations of hydrogen ions and hydroxyl ions in water is called an ionic product of water. It is given as-
• $K=[H^+][OH^-]$
• pH value has a range of 1 to 14. 7 is defined as the neutral range. Above 7 the basic character dominant and below 7 acidic characters dominated.
• As the temperature increases dissociation of water increases and the ionic product of water also increases.
