hydroxide is

B. basic

C.neutral

D. none of these​

Answer 1

Answer:

Explanation:

Question:-

The Solution of Sodium Hydroxide is:-

It is Basic.

But why?

• Let us understand it with a reaction.
• The Chemical Formula of Sodium Hydroxide is NaOH.
• We know that:-

$\rm{Acid+Base \longrightarrow Salt + Water}$

• So, let us take any Random acid.
• Random acid, let us say HCl (please do not try to use inky pinky ponky father had a donkey technique during exams. It will be a complete loss.)
• Verification:-

$\rm{\purple{HCl+NaOH \longrightarrow NaCl+ H_2O}}$

• We get Sodium Chloride as salt
• We get water.
• Hence, it is Base.

Other mineral Acids are Hydrochlorous Acid, Sulphuric Acid.

Another Technique:-

• We know Olfactory Indicators.
• If we put HCl, no change.
• If we put NaOH on Onion, then it gives a smell.
• This is another indicator that it is a base.
