How was chem p12 today? Expected gt?

Unfortunately no . I just can remember the concentration of NaOH which was 0.4 mol dm^-3 . I just glossed over the organic part (20-30). And I basically couldn't even read q.30.

Now we can discuss the paper I guess. What was the answer you guys gave to question no.29 where they asked the volume of Sodium hydroxide (NaOH) needed to react with ethanoic acid ? The options were perhaps like (A) 12.5 cm^3 (B) 25 cm^3 and unfortunately I don't remember the other options.

BIOLOGY PRACTICAL P34???? 26TH MAY

Well, I have 2 questions. (1) Will the no. of bubbles increase or decrease as the concentration of X inreases in Q.1? I mean what's the trend? (2) What is the approximate range of time taken to collect 2 cm^3 of oxygen gas also in Q.1?
