3Cu2O + 6AgNO3 + 3H2O
= 2Cu2H3O3NO3 + 2Cu(NO3)2 + 6Ag.
(Insoluble basic salt.)
[60] K2CrO4 + Pb(NO3)2 = PbCrO4 + 2KNO3
[61] Made by dissolving 12 grams of tartaric acid and 4 grams of stannous chloride in water, and adding potash solution till it is alkaline. The solution should remain clear on heating to 60° or 70° C.
[62] It must be remembered that arsenate of bismuth is completely insoluble in this acid.
[63] SbCl5 + 2KI = I2 + SbCl3 + 2KCl.
