Answer #1

Ans. The effectiveness of alcohol on bacteria is evaluated by the content of water the alcohol has. For eg., if seen  70 or 60 % Isopropyl alcohol is more effective than 100% because in 70 to 60 % the extra 30 or 40 % water acts as a catalyst. And pure alcohol is highly volatile and is evaporated within seconds whereas by adding water the volatility gets decreased and it stays on the surface for long allowing the alcohol to work its way on bacteria by breaking the envelope or cell wall causing the content to spill out and the protein to denature in the organism, thus killing the bacteria.
