Give the composition of an alloy called solder. State its one property and one use.

Open in App

Solution

The composition of the solder alloy is 50 per cent lead (Pb) and 50 per cent tin (Sn).
It has a very low melting point that is quite less than its constituting metals (Pb and Sn). Thus, solder is widely used in soldering and welding of electrical wires.
