A mixture is acidic if it has a pH below 7, and basic if it has a pH above 7. You can use pH paper or a pH meter to determine the pH of a mixture. Another way is to use indicators such as litmus paper (red for acids, blue for bases) or phenolphthalein (colorless for acids, pink for bases).
Litmus will allow you to tell if a solution is a acid or a base.
The simplest way is to use litmus paper. The mixture must be a liquid so that the mixture can react with the water and so dissociate into either hydronium or hydroxide ions. If it's a solid, try dissolving it in water. If you have a gas, use damp litmus paper. Red litmus paper is used to test for basic substances, and turns blue in a positive test. Blue litmus paper is used to test for acidic substances, and turns red in a positive test.
Lye is a strong base, which means it is basic, not acidic.

If one is acidic, and one is basic.
A pH test will tell you if it is acidic or basic. A pH test checks for the amount of H+ (hydromium) ions in solution. Higher amount of H+ ions means acidic, and higher amount of OH- means more basic.

The reason for a pH scale it to tell how basic or acidic a substance, or substance byproduct is.
