Question 1

As water is heated, its pH decreases. This means that:

◦ the water is no longer neutral.
◦ the Kw value is decreasing.
◦ the water has a lower [OH–] than cooler water.
◦ the dissociation of water is an endothermic process.
◦ None of these are correct.

Question 2

At 70°C, the ion-product constant of water, Kw, is 1.53 × 10–13 The pH of pure water at 70°C is:

◦ 7.000.
◦ 6.508.
◦ 5.828.
◦ 6.408.
◦ None of these are correct.
