Given 2NaOH+CuSO4->Cu(OH)2+Na2SO4

What does table of data have CuCl2 on data table instead of CuSO4.  Why is CuCl2 in the table proved by lab ?

 

I was absent during experiment and do not understand table given.

It seems that the data that you have is not complete.Please check the equation you had in class and the reactions that you have done in the laboratory. 

2NaOH+CuSO4->Cu(OH)2+Na2SO4 is a probable reaction and can be done in the lab. 

When you react CuCl2 with NaOH, the reaction would have been:

2 NaOH + CuCl2 -> Cu(OH)2 + 2 NaCl

Since you are not present during the lab activity, there may have some changes in the procedures. 

Hope this helps.
