Answer:
The H+ concentration is [tex]10^{-4.3} M[/tex]
Explanation:
We know that for any solution,
pOH + pH = 14
Given,
pOH = 9.70,
Therefore using formula,we get,
pH = 14 - pOH,
pH = 14 - 9.70;
pH = 4.30
We also know,
If Concentration of H+ in a solution in C,
Then,
pH = -log(C) ------(Formula 1) and C = [tex]10^{-pH}[/tex] ----(Formula 2)
Therefore,
using formula 2, we get,
C = [tex]10^{-pH}[/tex]
C = [tex]10^{-4.30}[/tex]M.
Therefore concentration of H+ in the given solution is [tex]10^{-4.3} M[/tex]
The concentration of the hydrogen ion [H⁺] in the solution having a pOH of 9.70 is 5.01×10¯⁵ M
pH + pOH = 14
pH + 9.7 = 14
Collect like terms
pH = 14 – 9.7
pH = 4.3
pH = –Log [H⁺]
4.3 = –Log [H⁺]
Multiply through by –1
–4.3 = Log [H⁺]
Take the anti-log of –4.3
[H⁺] = anti-log of –4.3
[H⁺] = 5.01×10¯⁵ M
