Front

What is the definition of a BASE according to Bronsted-Lowry?

Back

A substance that accepts a hydrogen (H+) ion.

Front

What is the range of the pH scale?

Back

0-14.

Front

What is known as the universal solvent?

Back

Water.

Front

What are the characteristics of a base?

Back

Bitter, slippery, indicator turns blue, pH greater than 7, produces hydroxide ions (OH-).

Front

What pH value is considered neutral?

Back

7.

Front

What is molarity?

Back

Molarity is a measure of the concentration of a solute in a solution, expressed as moles of solute per liter of solution (mol/L).

Front

What is solubility?

Back

Solubility is the ability of a substance to dissolve in a solvent at a given temperature and pressure.

Front

What is an acid according to Bronsted-Lowry?

Back

A substance that donates a hydrogen (H+) ion.

Front

What happens to the pH of a solution when an acid is added?

Back

The pH decreases, making the solution more acidic.

Front

What happens to the pH of a solution when a base is added?

Back

The pH increases, making the solution more basic.
