ANSWER:

Solution: Here, we are going to write the balanced chemical equation for the given reaction and find the precipitate that is formed. Also, we are going to identify the limiting reagent and calculate the mass of the precipitate formed. Step1: a) When a solution of 100.0 ml of 0.200 M KOH is mixed with a solution of 200.0 ml of 0.150 M NiS0 , po4ssium sulfate and nickel hydroxide are formed. The balanced chemical equation for the above reaction is given below: 2KOH(aq) + NiSO (aq) -------> Ni(OH) (aq) + K SO (aq) 4 2 2 4 Step2: b) From the guidelines of solubility, we can say that, out of the two products formed, i.e., Ni(OH) an2K SO 2Ni(4) is insol2le in water and will be precipitated. Thus the precipitate formed i
