1) Whats the molar solubility of MgCl2 (Ksp=8.8*10^-9) in HCl solution with pH 1.5 (detailed step please)

2) Which solution will increase molar solubility of CuCo3(s) at 298K? (Ksp of CuCO3 is 2.3 *10^-10, Ksp of Cu(OH)2 is 2.2 *10^-20)

i) HCl

ii) NaOH

iii) Na2CO3

I know NaOH is not the answer and Na2CO3 is part of the answer but why or why not the HCl be the answer? (I think it doesnt increase since won't give any mole but not sure)
