Answer 1

Concentration is defined as amount per unit volume of solution. When water is added to a base, the concentration of base decrease since volume of solution increases.Since there is an increase in volume of solution , but there is no change in amount of base thus now the same amount of base is present in more volume of solution, thus there is a decrease in concentration of base.
