Acid Titrations and pH

An alkaline material will have a pH of

• <7

• >7

• =7

An acidic material will have a pH of

• <7

• >7

• =7

If a material has an equal amount of H+ and OH- ions, then it is a(n)

• Acid

• Alkaline

• Neutral

If a material has more H+ ions, then it is a(n)

• Acid

• Alkaline

• Neutral

A chemist claimed that in Experiment 2, the pH of the sample solution was greater at a value of 0.2 mL of titrant added than at a value of 1.8 mL of titrant added. Do the results of Experiment 2 support this claim?

• No; at a value of 0.2 mL of titrant added, the sample solution was yellow, and at a value of 1.8 mL of titrant added, the sample solution was blue.

• No; at a value of 0.2 mL of titrant added, the sample solution was blue, and at a value of 1.8 mL of titrant added, the sample solution was yellow.

• Yes; at a value of 0.2 mL of titrant added, the sample solution was yellow, and at a value of 1.8 mL of titrant added, the sample solution was blue.

• Yes; at a value of 0.2 mL of titrant added, the sample solution was blue, and at a value of 1.8 mL of titrant added, the sample solution was yellow.
