In the second last question, the concentration of [OH-] SHOULD BE 7.2 * 10^-3 RATHER THAN 7.2 * 10^-5

[@penguinn__90]

Nope it's 7.2 x 10 ^ -5

[@uzair9426]

Love this man Even id dont watch his videos regularly but whenever I see It lights up my mood❤️

[@HangingQueen]

I watch your videos only for feel of chemistry which is not available in the schools Thank you sir♥

[@bhupendrayadav527]

.82 is correct answer

[@sazidalnoorzunaid]

finally found someone listened the Question carefully , sir told that same amount of H2S and HCl were mixed so the concentration would be (V*2*C*alpha + 0.3V)/2V)=0.15 than taking -log(0.15)=0.82 so ph=0.82 , thanks for the comment I didn't found single person who was talking about it

Answer to last question will be 1.3 *10^-20 = conc. Of H+ ion

[@Mohitthakurofficial]

In last question 2H+ conc @ equilibrium is 2.C.alpha It is not C.alpha

[@ashutoshpathak07]

YOU ARE WRONG STUPID

[@muskangupta3854]

2 Cα ayega Pr jb Cα zero hoyega to 2 bhi neglect hi ho jayega

[@yuvisonyy1962]

But ANSWER would remain same as at the end we have ti neglect that quantity

[@RohitYadav-ue8po]

Sir I was amazed to see your energy level while teaching. My coaching teacher has such a dull And low energy level due to which study becomes boring. I enjoy studying in your every lecture. Love you sir😍😍😍😍😍

[@its_naveen462]

Sir question solve karne ka method thoda lengthy he but app bahut sare questions ki practice karate ho to bo bhi yaad ho jata he or easy question to vese hi ho jate he😊
