Suppose you are studying the K sp of K C l O 3 , which has a molar mass of 122.5 g/mol, at multiple temperatures. You dissolve 4.00 g of K C l O 3 in 12 mL of water at 85 oC and cool the solution. At 74 oC, a solid begins to appear. What is the K sp of K C l O 3 at 74 oC?

The K sp Value is  

Explanation:

From the question we are told that

   The of is = 122.5 g/ mol

    The mass of dissolved is

    The volume of solution is  

The number of moles of is mathematically evaluated as

Substituting values

Generally concentration is mathematically represented as

For        

The dissociation reaction of  is

The solubility product constant is mathematically represented as

Since there is no ionic reactant we have

one state would change   like louisiana to texas. thats a change
