What is the [OH−] of a solution with pH 5.75?
Answers
ANSWER :
pH means potential of hydrogen and it is defined as the measure of concentration of hydrogen ions in a solution.
Mathematically, pH = -log[H^{+}]−log[H
+
]
Also, it is known that relationship between pH and pOH is as follows.
pH + pOH = 14
or pOH = 14 - pH
Therefore, putting the value of pH in the above relationship as follows.
pOH = 14 - pH
= 14 - 5.75
= 8.25
Hence, pOH = -log [OH^{-}]−log[OH
−
]
or, [OH^{-}][OH
−
] = antilog (-8.25)
= 5.62 \times 10^{-9}5.62×10
−9
Thus, we can conclude that the [oh−] of a solution with ph 5.75 is 5.62 \times 10^{-9}5.62×10^-9
