Question

Lead pipes are not suitable for drinking water because

• A. A layer of lead dioxide is deposited over pipes
• B. Lead reacts with air to form litharge
• C. Lead reacts with water containing air to form $Pb(OH{)}_2$
• D. Lead forms basic lead carbonate

Answer 1

The correct option is C

Lead reacts with water containing air to form $Pb(OH{)}_2$

Lead forms a hydroxide and thus contaminates drinking water. If we ingest this toxic water, it can wreak havoc with our bodies.
Excessive amount of lead elevates the risk for cancer, stroke, kidney disease, memory problems and high blood pressure. Young
children are particularly more prone to the toxicity as their growing bodies tend to absorb the toxin better.
