Question

When you add acid to a solution, _____. when you add acid to a solution, _____. the hydrogen ion concentration increases and lowers the ph the hydrogen ion concentration increases and raises the ph the hydrogen ion concentration decreases and raises the ph the hydrogen ion concentration decreases and lowers the ph?

Answer 1

Adding an acid raises the concentration of H3O+ions in the solution. Adding a base lessens the concentration of H3O+ ions in the solution. An acid and a base are like chemical dissimilars.

So in other words, this will increase the hydrogen ion concentration and lower the pH.
