a pale blue precipitate if formed.
-A pale blue precipitate is formed which is supposed to be insoluble copper carbonate. However, a flame test on the precipitate will be orange and I'm not sure why.
[I would assume why is because of excess sodium ions mixed in, sodium spectral lines and flame colors tend to overpower everything else.]

∙ 13y agoWhen copper (II) sulfate solution reacts with sodium hydroxide, a blue precipitate is formed. The equation for the reaction is:
CuSO4 + 2NaOH -----> Cu(OH)2 + Na2(SO4)
Cu(OH)2 is responsible for the blue color.

How much arsenic III nitrate and sodium sulfide do you need to make 1gram arsenic sulfide?
The balanced reaction should look like this: 2Ar(NO3)3 + 3Na2S Ar2S3 + 6Na(NO3) The molar weight of arsenic sulfide is 176.091 g/mol. 1 gram of arsenic sulfide therefore constitutes 0.006 mol. The stoichiometry of the above chemical reaction indicates that 2 moles of arsenic nitrate and 3 moles of sodium sulfide are required to make 1 mole of arsenic sulfide and 6 moles of sodium nitrate. These numbers are the ones that appear in front of the chemicals and are called the stoichiometric coefficients. You therefore need 0.012 mol of arsenic nitrate and 0.018 mol of sodium sulfide. The molar weights of these compounds are 132.959 g/mol and 78.043 g/mol respectively. Multiplication then gives you the answer which is 1.596 g of arsenic nitrate, and 1.405 g of sodium sulfide.
