pOH of resulting solution is 0.086
Explanation:
KOH and CsOH are monoacidic strong base
Number of moles of
in 375 mL of 0.88 M of KOH =
= 0.33 moles
Number of moles of
in 496 mL of 0.76 M of CsOH =
= 0.38 moles
Total volume of mixture = (375 + 496) mL = 871 mL
Total number of moles of
in mixture = (0.33 + 0.38) moles = 0.71 moles
So, concentration of
in mixture,
= ![\frac{0.71}{871}\times 1000M=0.82M](/tpl/images/0538/8908/cb3c6.png)
Hence,![pOH=-log[OH^{-}]=-log(0.82)=0.086](/tpl/images/0538/8908/1f1db.png)
