Question

Ph effect in water solubility of calcium carbonate

Answer 1

Answer:

17.4.1.1 Calcium Carbonate

Increasing CO2 also makes the water more acidic and decreases the pH. The calcium carbonate scaling usually occurs with a pressure drop, for example, at the wellbore. This reduces the partial pressure of CO2, thereby increasing the pH and decreasing the CaCO3 solubility.

Answer 2

Answer:

17.4.

Increasing CO2 also makes the water more acidic and decreases the pH. ... This reduces the partial pressure of CO2, thereby increasing the pH and decreasing the CaCO3 solubility. The solubility of calcium carbonate decreases with increasing temperature.
