Acids, Bases, and Salts Online Test

Bases are defined by their ability to increase the concentration of hydroxide ions in solution.

Acids are characterized by their ability to turn blue litmus paper red.

A pH of 11.0 is greater than 7, which indicates a basic solution.

Pure distilled water has a neutral pH of approximately 7.0.

The pH scale is logarithmic; values further from 7 indicate higher concentrations of H+ ions, meaning a stronger acid.

A pH of 9.0 is greater than 7, which classifies the substance as a base.

A pH of 2.4 is less than 7, which classifies the substance as an acid.

Both strong acids and strong bases are chemically corrosive and can damage skin and materials.

Distilled water is neutral with a pH of 7.0.

The pH range from 0 to 6.9 represents acidic solutions.

A slippery feel is a characteristic physical property of bases.

A bitter taste is a characteristic property of bases.

Acids are defined as substances that increase the concentration of H+ (hydronium/hydrogen) ions in water.

Neutralization is the reaction between an acid and a base to form water and a salt.

The general equation for neutralization is Acid + Base -> Salt + Water.

Acids, bases, and salts are all electrolytes, meaning they dissociate into ions in water and conduct electricity.

Bases are substances that turn red litmus paper blue. Acids turn blue litmus paper red.

Acids are characterized by their sour taste. Bases typically taste bitter and feel slippery.
