Alsalam alykum miss, can you please tell me how you knew that there was NaOH excess in this question 1:01:41 , I always get these buffer questions wrong because of it.

[@106four]

Because at that volume the titration is past the neutralization point and is starting to become more basic, so the base is in excess

[@zaidaljanabi7642]

@@106four do you know that from the graph that they gave or how?

[@noorsalehun]

Could anyone explain question 6?

[@fakhirrehan8869]

At 1:05:41 isnt it in the formula (acid)/(salt)

[@picklefibre9831]

the coefficient of log is taken to the power to make log positive so the reciprocal of the acid/salt = salt/acid

[@ruweidaahmed1323]
