A basic solution is an aqueous solution containing more OH-ions than H+ions. In other words, it is an aqueous solution with a pH greater than 7. Basic solutions contain ions, conduct electricity, turn red litmus paper blue, and feel slippery to the touch.

Examples of common basic solutions include soap or detergent dissolved in water or solutions of sodium hydroxide, potassium hydroxide, or sodium carbonate.
