Uff this is a tough one...is there any vol. given?Q. Which ion is present in the highest concentration in a 2mol/dm3 aqueous solution of sodium sulphate?
A. hydrogen ion H+
B. hydroxide ion OH-
C. sodium ion Na+
D. sulphate ion SO4^2-
the answer is Na+ ion (please explain how)
Sodium. Sodium sulfate produces 2 Na ions and 1 sulfate ion when ionization occurs in the dissolving processQ. Which ion is present in the highest concentration in a 2mol/dm3 aqueous solution of sodium sulphate?
A. hydrogen ion H+
B. hydroxide ion OH-
C. sodium ion Na+
D. sulphate ion SO4^2-
the answer is Na+ ion (please explain how)
Because the formula is Na2SO4Uff this is a tough one...is there any vol. given?
oh right.....Because the formula is Na2SO4
2 Na+ ions will be dissociated..while others will be 1 each (OH- , SO4 2- , H+ )
daredevil
Same problem but i manage them smehwCan anyone help me with the combustion of alkanes , alkenes , alcohols equations ???? balancing them is real tough :/ in high values :/ !! can anyone tell any method to do so ??
it takes abt 10 mins jus fo 1 markSame problem but i manage them smehw
oh right.....
just write the formulae and balance the product side then do the alkane alkene and last oxygen works wonders for meCan anyone help me with the combustion of alkanes , alkenes , alcohols equations ???? balancing them is real tough :/ in high values :/ !! can anyone tell any method to do so ??
it was Option F.what was the ansswer to the lowest centre of gravity one
what was the ansswer to the lowest centre of gravity one
i drew the question about the field lines from positive to negative but some were outside the page. will they deduct marks
oh DARN!! i did that and then crossed it out bcuz i thought thta i was ust assuming there is one Cl but there cud have been 2 or more. :/
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
