Hello, for dii) if solubility has decreased due to common ion effect, doesn't that increase the concentration?

[@i.love.theamkl]

in (e)(ii), the formation of more solid will not increase the solid concentration. You need to understand the concentration of solid is always constant. The concentration here means the amount of solid that "dissolved" to form the respective ions.

hi. as you said in the start if we add OH it will react with C6H5COOH. i wanted to ask why will it not react with the negative C6H5COO ion in product side or why it will not react with H+ ions to neutralize it?

[@i.love.theamkl]

You need to understand how the buffer solution works. OH- is a base and it will react with the acid. Normally we don't use H+ as it is not the buffer species.

@@i.love.theamkl thankyou for replying and helping out

[@Elpsycongroo1130]

1:59 is it wrong if I mention just h+ and oh-

[@i.love.theamkl]

the answer just not specific enough, means too general as it is not involving buffer species.
