Acids and Bases

If the pH of a solution is 5.6 the pOH is

• 6.5
• 12.4
• 8.4
• 5.6

A  pH and a pOH will add up to:

• 0
• 7
• 14
• 1.0 x 10^-14

Which is the correct set of acid properties, as described by Boyle:

• sour taste, corrosive, change litmus from red to blue

• sour taste, corrosive, change litmus from blue to red

• sweet taste, slippery, change litmus from blue to red

• sour taste, slippery, change litmus from blue to red

Neutral solutions have a pH of:

• 0

• 1

• 7

• 14

Which is true?

• pH of less than 7 is basic; pH of more than 7 is acidic

• pH of less than 7 is acidic; pH of more than 7 is basic

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