An experimental procedure requires 10 ml of acid to be dissolved into a beaker of water. an additional 5 ml of acid is added to the solution. which statement best describes the new solution? the strength of the acid in the solution has been increased the concentration of acid in the solution has decreased by one half the concentration of acid in the solution has been increased the strength of the acid in the solution has decreased by one half

The correct statement is that the concentration of the acid in the solution will increase.

Explanation:

On the basis of the given question, if one dissolves 10 milliliters of acid in a beaker of water, the acid will get diluted. As the number of moles of acid is not going to change, thus, one can use the formula:  

M1V1 = M2V2

Here, M is the concentration of the acid in the solution,  

V1 = 10 ml

V2 = V water + 10

If we supplement, an other 5 ml of acid, the new concentration of the acid will be:  

M = M1 (5 ml) + M2 (Vwater + 10 ml) / (5 ml + V water + 10 ml)

Therefore, the concentration of the acid in the new solution will increase.
