Chemistry: Acids and Bases

NaOH is:

• an Arrhenius base

• an Arrhenius acid

• neither an acid nor a base

• both an acid and a base

The following statement is true for arrhenius acid and base EXCEPT

• Arrhenius acid produces H⁺ ions
• Arrhenius base produces OH^- ions
• H₂O need to be present for arrhenius acid base to dissociate
• Hydrogen atoms that make the solution acidic

a compound that increase H+ or H3O+ concentration by making the solution more acidic is called

• arrhenius acid

• arrhenus base

True or false: bases are sometimes called alkaline.

• True

• False

Neutral solutions have a pH of:

• 0

• 1

• 7

• 14

True or false: a neutral solution has equal amounts of H⁺ and OH^-.

• True

• False

Vinegar, fruit juice, and cola are examples of:

• strong acids

• strong bases

• strong bases

• weak acids

NaOH may be found in drain cleaners and as a component of soaps. Is NaOH an acid or a base?

• Acid

• Base

• Neither (Neutral)

Water found near sources of air pollution tends to be:

• Acidic.

• Basic.

• Neither. Air pollution doesn't alter the pH of water.
