someone can confirm no titration would be nice tbh other than h202 or starch

dude firstly they will give the the error with you most of the time , while sometimes you have to find it yourself which is the least count and if you have take two values such as a tritrate which requires the subtraction of inital and final volumes then you need to multiply the least count by 2.Ok so no one wants to reply me regarding the error thing, i totally understand, its the last day but please confirm this.
2 d.p balance uncertainty = +-0.01 g
measuring cylinder = +- 0.5 cm3
burette = +-0.05 cm3
thermometer = +-0.5 *C
we multiply this by number of readings divided by our reading then x 100, to find % error. Correct? That's all i need to know regarding errors and uncertainties?
Thanks Alot! Can you confirm if my uncertainties are correct.. I am confused about the 2d.p balance.. is it 0.01 or 0.005?dude firstly they will give the the error with you most of the time , while sometimes you have to find it yourself which is the least count and if you have take two values such as a tritrate which requires the subtraction of inital and final volumes then you need to multiply the least count by 2.
No its 0.01Thanks Alot! Can you confirm if my uncertainties are correct.. I am confused about the 2d.p balance.. is it 0.01 or 0.005?
Please tell usNo. You will get H2O2 rates of reaction using the starch indicator. Anywayz, I can confirm one practical that might come, but will I get banned if i TELL IT?
he did mention similar types of questions belowPlease tell us
I cannot. Its illegal. Only thing confirmed is H2O2. Al3+ and Mn2+ ions are not present 99% chance. NOT PRESENTPlease tell us
Just tell us this , Is tritration coming? or is the rate of reaction coming? or is it the enthalpy change coming?I cannot. Its illegal. Only thing confirmed is H2O2. Al3+ and Mn2+ ions are not present 99% chance. NOT PRESENT
Man HOW THE HELL DO YOU THINK IT'S ILLEGAL!? It is totally not! if you do not want to post here, please please Private message us.I cannot. Its illegal. Only thing confirmed is H2O2. Al3+ and Mn2+ ions are not present 99% chance. NOT PRESENT
if those are the first 2 q's then salts must be sodium carbonate and copper sulfate. But... where will be sodium thiosulfate be used then?HERE IS THE PREDICTION
1) Rates using H2O2 and Starch And KI
2) Enthalpy between Mg and acid
3) Qualitative analysis (Salts unknown/disputed)
I think its also going to be used for rate of reaction.if those are the first 2 q's then salts must be sodium carbonate and copper sulfate. But... where will be sodium thiosulfate be used then?
That's rightI think its also going to be used for rate of reaction.
BE OUR SAVIOUR btw homie the papers arent leaked so these are all guesses hence its perfectly fine . and tell us all the ions not present that way youre not telling the answer xDI cannot. Its illegal. Only thing confirmed is H2O2. Al3+ and Mn2+ ions are not present 99% chance. NOT PRESENT
haha, you nailed itBE OUR SAVIOUR btw homie the papers arent leaked so these are all guesses hence its perfectly fine . and tell us all the ions not present that way youre not telling the answer xD
what about the one question you knew xDOk guyz. According to Hassan's picture posted,
sir said 60% chance of rates , 40% chance of titration.
Tyoe iodometric with CuSo4 in google
Also small enthalpy might come if it is rate, but a bigger one might come if it is titration.
Qualitative Analysis Notes : Mn2+ or Al3+ wont be present it seems (not reliable)
