Question

if ph of NaOH is 10, calculate its molarity.​

Answer 1

We know that:

pH + pOH = 14

Given that: p

H

=10

p

OH

= 4

pOH

= - log [OH

−

]

antilog (-4) = [OH

−

] =0.0001 M

Answer 2

13

$\huge{ \mathfrak{\purple{Explanation}}}$

Given

ph of NaOH is 10

To Calculate

Morarity of NaOH

We can calculate pOH = - log [OH-]

= - log [10-1]

= 1

And remembering that,

pH + pOH = 14

we get, pH = 14 - 1 = 13.
