Volume percentage is the percentage of volume of interested compound from the whole volume of the solution. volume percentage of isopropyl alcohol can be calculated as follows; volume percentage (v/v%) = volume of alcohol/ total volume of solution x 100% total volume = 135 + 745 = 880 mL substituting the values , v/v % of alcohol = 135 mL / 880 mL x 100 % answer = 15.34 %
You have an acid that is acidic or a base that is basic. When you mix the two, they form water (assuming those are bronsted-lowry acids and bases) which is neutral.
