ques
A) 0---- 23
10 ---- 25
20 --- 27
30 ---
i think u r smart enough to do ques a , b and c part
for d)
temp at 6cm3 for the exp1 graph
e)i)cn be answere easly if u work out ,by looking at graph or the tabel
ii)the acid would be mre concentrated or would be a stronger acidd
i think i wrote both in my exam
f)so that no traces of acid c would involve in result of experiment 2
to get fair and accurate result
g)25, wont decrease much as the exothermic acid-base reaction is completed, it would remain at 25 because any increase or decrease in temp due to exp would finally reacha t room temp (25 avg) as it looses or gains heat form the atmosphere
HOPE U UNDERTAND THE ANSWERE
any furhter doubts infrm me
