in acid base any indicator can be used

 

[rockpapers]

great thankyou almost the same answers but while naming the indicator you will have to give the range so that you may may clear for why you chose the particular indicator

yes definitely!!!

 

[rockpapers]

sorry the rate is always positive

No rate of reaction can certainly be negative!!!

 

[rockpapers]

Your rate of reaction is not negative... Its always positive dude...

Rate of reaction can for sure be negative!!!!!!

Dilution factor 200?? If it is 200, your final solution will have a concentration of 5/200 = 0.025moldm-3. You don't use that formula c1v1 = c2v2 here. Original solution is 5moldm-3. A volume of it is to be diluted to get 1moldm-3. So dilution factor is 5 or 1/5.

bro giving the formula is necessary in order to explain the actual methode or else marks would be deducted

my partition coeff was greater than 1 since i wrote conc of nh3 in water/ conc of ammonia in trichloro
and for the reason why titration wasnt done using trichloromethane, i wrote just because conc of nh3 is too low in it very little vol of h2s04 will titrate with it giving more percentage error.

you wrote the formula incorrect it should be tricloromethane/water

you wrote the formula incorrect it should be tricloromethane/water

if its less than 1 why he gave the partition coeff as 25 in the next part. :/

Lol of course i did la...lol

bro what ever u did is fine you will loose one mark for the dilution factor and stop posting the answers without confirmation of anything and i was confused about the rate being negative aswell i changed it to positive cause the inital rate gradient would always be negative and in all calculations i saw positive answer :/ . my factor cam nearly 1/5 but a little less ( you also had to include the volume of NH3 in the CHCl3 i guess) . i am loosing around 2-3 marks but i am happy

 

[TANJIAHOU]

Lol.. Stop it.. Get over with it..
