Adding an acid to a solution will lower it's Ph, but adding a base will raise it's Ph.

Adding an acid base indicator to a sodium hydroxide solution can verify that it is an alkaline solution. For example, phenolphthalein turns pink in an NaOH solution.

To prepare a dilute solution.
Adding base will increase pH-level
Adding a base to the solution.
Adding a base the pH increases.
Adding a base will make the pH go up (increasing of OH- ions concentration).
When adding a strong acid to an acidic solution pH decreases. Adding a strong base to an acidic solution the pH increases.
Adding an acid base indicator to a sodium hydroxide solution can verify that it is an alkaline solution. For example, phenolphthalein turns pink in an NaOH solution.
