Chemistry Paper 4 (ATP) Discussion

[bamteck]

The question on electrolysis was similar to that of June 1999, isn't it?

 

[usama1993]

what was the answer of the last part in the last question that was that " how we could get more mass of silver deposited on cathode "

The answer was : USE A ANODE MADE OF SILVER

thanks usama but there would be many answers to this question

i wrote use of molten silver nitrate instead to aq. silver nitrate

by using molten silver nitrate the ions of silver would increase so more would develope on cathode


the font with the blue one i didint wrote in exam
i only wrote the red font part
yeah...i hope so

is my answer correct :/

 

[usama1993]

By increasing current i think u would only increase the rate at which silver is deposited, not the amount

excatly , that would not increase the mass of silver deposited on cathode

PALS,rose and usama answers seems to be sensible and would be given credit

thnx

hey p[rince....
what was the question of last MCQ to which u have worte answer ALL METALS ?????

 

[bamteck]

@ PRINCE ::: fifth MCQ was only the first two metals because copper doesn't react with HCI

yeah...rite:
thnx

 

[Heshna]

@ bamtek Im sitting for computer studies 7010... u ???

 

[bamteck]

@ Heshna :: Yea me alsO.. Do u think working out some 15 xams papers will help me to achieve a good credit?

 

[karthik]

the paper was very easy...In fact it was easier than p2...the correction is going to be severe..!!

no corection will be normal only the grade marks will go high .... 80%=A

 

[karthik]

what was the answer of the last part in the last question that was that " how we could get more mass of silver deposited on cathode "

The answer was : USE A ANODE MADE OF SILVER

Or u can write use a higher concentration of aques silver nitrate
