+solved @user1 @user2...
to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.ques is wrong ??
1. solubility of salt (na2c2o4 ) is found not acid (h2c2o4)
2. Ksp not given
Common ion effect!
You can find ksp from this data. 4s3, s is given to be 1.06
Also, this forms a buffer
Yes... that's where I was confused. The ans key says the ans is D... I was getting B as the answer
oh rightt
We'll use pH = pka1+pka2/2 to get the H+ concentration right? And then (0.2+s) times the calculated value of H+ squared... and equate it to the Ksp we calculated using the given conc. Is this right? Or am I going wrong somewhere?
I feel B too should be right.
But that is without calc haha. Guesstimate.
we good?
