• The concentration of solutes in a solution.

Give an example of an acid-base reaction.

• HCl + NaOH → H2O + NaCl

• CaCO3 + HCl → CaCl2 + CO2 + H2O

• NH3 + HCl → NH4Cl

• H2SO4 + NaOH → Na2SO4 + H2O

Which of the following is a strong acid?

• Hydrochloric acid

• Citric acid

• Carbonic acid

What is the primary characteristic of a base?

• It tastes sour.

• It feels slippery.
