Question

KSP(CaC2O4) = 2.310–9; KSP(CaCO3) = 3.810–9; KSP(CaSO3) = 3.210–7. Arrange the following substances in increasing order of their solubility​

Answer 1

я не знаю, я тупая, извени нечем помочь не смогу

Answer 2

To arrange the substances in increasing order of their solubility, we need to compare their solubility product constants (Ksp) because the lower the Ksp, the lower the solubility of the substance. Here are the Ksp values you provided:

1. Ksp(CaC2O4) = 2.31 x 10^(-9)
2. Ksp(CaCO3) = 3.81 x 10^(-9)
3. Ksp(CaSO3) = 3.21 x 10^(-7)

Now, let's arrange them in increasing order of solubility:

1. CaSO3 (Ksp = 3.21 x 10^(-7))
2. CaCO3 (Ksp = 3.81 x 10^(-9))
3. CaC2O4 (Ksp = 2.31 x 10^(-9))

So, from least soluble to most soluble:

1. CaSO3
2. CaCO3
3. CaC2O4
