Will the solubility of KCL change in NaCl solution? Would the solubility of KCL change in NaCl solution?
5 G of NaCl has been dissolved in 100 g of water. If KCl is added to the solution until it is saturated, the solubility of NaCl will decrease due to the co-ion effect if K2CO3 is added, the solubility of NaCl increases due to the salt effect.
