Text Solution

Verified by Experts

Sodium zincate is formed
`ZnO + 2NaOH rarr Na_(2)ZnO_(2) + H_(2)O`
ii . Stamous chloride is a good reducing agent it reduced iodine to iodidu.
`SnCI_(2) + 2HCI + I_(2) rarr SnCI_(4) + 2HI`
iii. Sodium sulphate is formed
`SO_(2) + H_(2)O + (1)/(2) O_(2) + 2NaCI rarr Na_(2)SO_(4) + 2HCI`
