How will the addition of water affect the acidity of a highly acidic solution having ph 2? . a) there will be a slight decrease in the ph value. b) there will be a slight increase in the ph value. c) the ph value will remain constant.

The addition of water to the solution slightly decreases the concentration of the hydrogen ion in the solution. As pH is dependent to this, it will also change. The decrease in the concentration will increase the pH value. Thus, the answer is letter B.
