pH Calculations

The pH scale is a range from:

• 1-7
• 0-14
• 1-5
• 1-20

A(n) ______ is a substance with a pH less than 7

• Acid
• Alkaline
• Base
• Buffer

A(n) _______ is a substance with a pH greater than 7.

• Base
• Acid
• Buffer
• Water

What is the only substance with a neutral pH of 7?

• Milk
• Orange Juice
• Water
• Blood

A base is a substance

If the [H+] of a solution is 1 x 10^-2 mol/L the pH is

• 2
• 12
• -2
• 1

If the pH of a solution is 5 the [H+] is

• 1.0 x 10⁵  M
• 1.0 x 10⁹  M
• 5.0 x 10¹  M
• 1.0 x 10^-5  M

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

if the [H+] of a solution is 1.0 x 10^-2 mol/L the pH is

• 2
• -2
• 1
• 12
