Question

Why sodium hydroxide is much more soluble than sodium chloride?

Answer 1

Answer:

Ionisation of NaOH (sodium hydroxide)

NaOH ------ Na+ ion and OH - ion

Ionisation of Nacl ( sodium chloride)

Nacl ------- Na+ and Cl-

here oH are much smaller than Cl , and OH able to make hydrogen bond with the water so NaOH is dissolved easily and more soluble than Nacl ..

this is your answer..
