Write the equation for the dissolution of each of the following in water, and then indicate the total number of moles of solute ions formed.
A) Each mole of Rb₃PO₄ will release: 3 moles of Rb⁺ 1 mole of PO₄⁻³ So a total of 4 moles of ions are released per mole. If there are 0.5 moles, 2 moles of ions will be released.
B) Each mole of Cr₂(SO₄)₃ will release: 2 moles of Cr⁺³ 3 moles of SO₄⁻²
So a total of 5 moles of ions are released per mole. When there are 0.5 moles, 2.5 moles of ions will be released.
