Answer: The pH value of the solution is 10 and the solution is basic in nature.
Explanation:
To calculate the pH of the solution, we need to determine pOH of the solution. To calculate pOH of the solution, we use the equation:
[tex]pOH=-\log[OH^-][/tex]
We are given:
[tex][OH^-]=1\times 10^{-4}M[/tex]
Putting values in above equation, we get:
[tex]pOH=-\log(1\times 10^{-4})\\\\pOH=4[/tex]
To calculate pH of the solution, we use the equation:
[tex]pH+pOH=14\\pH=14-4=10[/tex]
There are three types of solution: acidic, basic and neutral
To determine the type of solution, we look at the pH values.
As, the pH of the solution is 10 and is lying in the range of basic solution, so the solution is basic in nature.
The pH value is mathematically given as
pH= 10
The pH value is above 10 which signifies that the solution is alkaline (basic).
Question Parameters:
A solution contains 1 × 10⁻⁴ M OH⁻ ions.
Generally the equation for the pOH is mathematically given as
pOH = -log [OH⁻]
Therefore
pOH = -log 1 × 10^{-4}
pOH = 4
Therefore pH is
pH + pOH = 14.00
pH = 14.00 - pOH
pH= 14.00 - 4
pH= 10
Hence, the pH value is above 10 which signifies that the solution is alkaline (basic).
