Question

Question 4 2 pts Which of the following will be more soluble at low pH than in pure water? O Cu(NO3)2 Ο ΚΙ O AgCI o MgSO4 o Fe(CIO4)3

Answer 1

A strong acid has conjugate base which is weaker in nature

for example HCl is strong acid so it has conjugate base Cl^- which is weaker in nature

similar is the case with I^- .

So this concept is applied in the given answer below
Basic pH since * Cu(NO3) = ² + 2NO3 * It will be more soluble in of cult ton (OH)2 80 more soluble in Fiqhzel pH Not soluble in low pH

* Agcl will not have any effect on lowering PT Agci —Agt + c Cī ius conyugate Base of strong acid so its weak Base and . ci will not react with it 80 Agc) unaffected by lowering pH. 42 Masou will more soluble in low pH than water MgSO4 = Mg2+ + 502 when btb, soll +ht = HSCT it will be slightly more soluble im loov pH

Similar In the case of AgCl we can apply in the case of KI as well that its conjugate base I^- is weaker so will not react that much which will make its solubility low in lower pH .

So we can say that MgSO₄ is one among these which can have slightly higher solubility at lower pH compared to all these .

3+ * * Fe(Clou)3 = fet + 3010 clou is also weak conjugate base of Helou & it will not react with it (low PH) So not soluble in lower pH
