@Newton Do you know how NMR spectroscopy works? Agar nahi tho uske baare mein math socho..

What is the $p^H$ of $0.1 M$ $\ce {NaHCO_3}$ solution if $p^{ka_1} $ and $p^{ka_2}$ of $\ce{H_2CO_3}$ are $7$ and $11$?
Now I know this is pretty standard problem but I can't find the solution anywhere
Any ideas anyone?

@HrishabhNayal use the hydrolysis formula: pH = 1/2(pKw + pKa + log C), here pKa would be pKa1

@Safdar No i never asked anything about NMR. My only question is "When CH3 is directly attached to O(e.g. methoxide) then CH3 acts as Electron Withdrawing Group ?"
Is it true ??

@Newton Haven't heard about it, but how would it make a difference since now the O is the actual -I group and not the CH3-. It gives no extra value..

@Safdar OK thanks.
