17. Increasing the pH of an aqueous solution will cause carbonate mineral solubility to: (a) increase (b) decrease 18. The solubility of carbonate minerals in low pH aqueous solutions increase with: (a) increasing temperature and increasing partial pressure of CO 2 (b) decreasing temperature and increasing partial pressure of CO 2 (c) increasing temperature and decreasing partial pressure of CO 2 (d) decreasing temperature and decreasing partial pressure of CO 2.
