Guys, if you have any idea regarding tomorrows chemistry practical, please tell. God bless you.

Thankyou so much. Wish you all the luck for it too. If you get any idea ragarding. Please tell.having mine as well wish you luck...
I wrote diprotic, the ratio of hydrogen ion and Z was 1:2. Thats what i did. What about you?how was the paper? was the acid monoprotic or diprotic?
yes i wrote the same thingI wrote diprotic, the ratio of hydrogen ion and Z was 1:2. Thats what i did. What about you?
did you manage to determine the anions?How did you all do ? I found the last question quite tricky
Couldnt finish it on timedid you manage to determine the anions?
yea i got those cations as well, my friends said that FA8 anion was an unknown while FA9 anion was carbonate...Couldnt finish it on time
Got mg 2 + ,ammonium as the cations though
For the accuracy one i wrote that we should use more anount of reagent fa3 in that case i guess, as it will reduce the percentage uncerntainity.what did you guys write for the last two questions on enthalpy change questions page??
first one was about accuracy
and the second was about HCl being more exothermic than monoprotic acid(H2SO4)?
Mine was mg2+ and then it was nh4+ and cl-, most of my friends had these so idk really.yea i got those cations as well, my friends said that FA8 anion was an unknown while FA9 anion was carbonate...
yep I wrote the same except I didn't mention it will reduce percentage uncertainty though. Hope I don't lose a mark there.For the accuracy one i wrote that we should use more anount of reagent fa3 in that case i guess, as it will reduce the percentage uncerntainity.
And i don’t remember what i wrote for the other one.
this isn't a salt. as both of them are solutions so i think you cannot change the amount . else concentration could have been increased so as to have high increase in temperature. so that there is less percentage error while calculating temperature.....yep I wrote the same except I didn't mention it will reduce percentage uncertainty though. Hope I don't lose a mark there.
I guess it did. as you have to mention how will it make the experiment more accurateWont this be correct : carrying out the experiment in a closed chamber ? Did it say to give reason as well ?
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
