Question

Give any two points of difference between hydrochloric acid and sodium hydroxide.​

Answer 1

NaOH (sodium hydroxide) is also a base. When we react sodium carbonate with hydrochloric acid they will react and neutralize each other, in a neutralization reaction. But on the other hand two bases will not react with each other. Thus we can distinguish between HCl and NaOH as one will react will Na2CO3 and one won't.

Answer 2

--HCl

a.) it is acidic in nature.

b.)HCl reacts with solid Ha2CO3 to liberete CO2 gas .

--NaOh

a.) it is basic in nature.

b.) No reaction is observed when NaOH is added to solid Na2CO3
