प्रश्न

How would you show that silver is chemically less reactive than copper?

Advertisements

उत्तर

When silver is dipped in a copper sulphate solution, no reaction occurs. This means silver cannot displace copper from the copper sulphate solution. Hence, it shows that silver is chemically less reactive than copper.
