Given the following equilibrium for the dissoluton of calcite,
CaCO3 (Quant Analysis)
Given the following equilibrium for the dissolution of calcite, CaCO3 H2O ←→ H++ OH' ; Kw 2+ 1. Use the systematic approach to equilibrium to derive a mathematical expression for [Ca?] concentration in terms of [H], Ksp, K1 and K2 2. Use your textbook to get values for Ksp, K and K and then calculate the solubility of Caco, at pH 8.
