Cupric ammonium sulphate was found to contain
water of crystallization by mass. Upon
strongly heating, it gave cupric oxide corresponding
to of starting mass. Find the empirical
formula of cupric ammonium sulphate.
water of crystallization by mass. Upon
strongly heating, it gave cupric oxide corresponding
to of starting mass. Find the empirical
formula of cupric ammonium sulphate.
View answer and explanation
Correct option: A
Option A is correct because the empirical formula is CuSO4.(NH4)2SO4.6H2O, which is derived from the mass percentages of water and cupric oxide.
