Ratio of water molecules of Potash alum to Mohr's salt is ?
Number of water molecules in Mohr's salt is
The formula mass of Mohr's salt is 392. The iron present in it is oxidised by KMnO_(4) in acid medium. The equivalent mass of Mohr's salt is :
STATEMENT-1 : The equivalent mass of Mohr's salt is (M)/(4) [If M is molecular mass of Mohr's salt] and STATEMENT-2: The normality of Mohr's salt is higher than molarity for same amount and volume at constant temperature.
How many ions per molecules are produced in the solution when Mohr's salt is dissolved in excess of water ?
A sample is a mixture of Mohr's salts and (NH_(4))_(2)SO_(4). A 0.5 g sample on treatment with excess of BaCl_(2) solution gave 0.75 g BaSO_(4) . Determine percentage composition of the salt mixture. What weight of Fe_(2)O_(3) would be obtained if 0.2 g of the sample were ignited in air?
