This question concerns a hydrated double salt A: Cu(NH4),(SO4)y.ZH,O; whose formula may be determined from the folowing experimntal data. a) 2g of salt A was boiled with excess sodium hydroxide and the ammonia expelled collected by absorption in 40 cm of 0.5 M hydrochloric acid in a cooled flask. Subsequently this solution required 20 cm of 0.5M sodium hydroxide for neutralization. i) Calculate the number of moles of ammonium ion in 2g of salt A. ii) Calculate the mass of ammonium ion present in 2g of salt A.
