Please correct answer and don't used hand raiting

Use the systematic treatment of equilibrium to determine the pH and the concentrations of all species in a saturated aqueous solution of SrF2. Do not include activity coefficients. The solubility of SrF2 is governed by Ksp for the salt, hydrolysis of F- and of Sr2+, and by ion pairing between Sr2 + and F-. PK(SrF2) = 8.58, PK(HF) = 3.17, pkw = 14.00, pk for the formation of (SrOH+) = 13.18, pk for the formation of (SrF+) = 0.14 Show all your work and upload your answers here. 1 - Write the pertinent reactions. 2 - Write mass balance and charge balance equations. 3 - Write the equilibrium constant expressions. 4 - Count the equations and unknowns. 5- If the problem is solvable make suitable approximations and find the concentrations and the pH.
