If a precipitation reaction occurs when a solution of one species is added to a solution of the other, enter the formula, including the state, of the soluble product. If there is no reaction, enter the formula and state of all ions in solution, separate by comma.
CoCl2(aq) + Li3PO4(aq) →
To determine the soluble product or the ions in solution, we first need to check the solubility rules. These rules will tell us whether the resulting compound is soluble (will stay in solution) or insoluble (will form a precipitate).
Looking at the reactants:
CoCl2(aq) - This is a soluble compound since most chloride (Cl-) salts are soluble.
Li3PO4(aq) - This compound contains a phosphate (PO4^3-) ion, which makes it insoluble when paired with most metal ions, including lithium (Li+).
Based on the solubility rules, we can predict that a precipitation reaction will occur because Li3PO4 is insoluble.
To find the formula and state of the soluble product or the ions in solution, we need to determine the products of the reaction.
The balanced chemical equation for the reaction is:
CoCl2(aq) + 3Li3PO4(aq) --> Co3(PO4)2(s) + 6LiCl(aq)
From this equation, we can see that Co3(PO4)2 is the resulting product, and it is in a solid state (s). LiCl is also formed as a soluble product, indicated by (aq).
Therefore, the formula of the soluble product is Co3(PO4)2(s) and the formula and state of the ions in solution are 6Li+(aq) and 6Cl-(aq), respectively.
