Answer:
<h2>12.1 </h2>
Explanation:
Since the pH has been given, the pOH can be found by using the formula
pH + pOH = 14
pOH = 14 - pH
From the question we have
pOH = 14 - 1.9
We have the final answer as
<h3>12.1</h3>
Hope this helps you
Answer:
Option (E) is correct
Explanation:
Solubility equilibrium of is given as follows-
Hence, if solubility of is S (M) then-
and
Where species under third bracket represent equilibrium concentrations
So, solubility product of ,
Here,
So,
So,
Hence option (E) is correct
