3akshay equivalents of NaOH is half of that of the equivalents of Ca(OH)2
1 gm mix of NaOH and Ca(OH)2 gets completely neutralised by x ml 1 M HCl solution the value of x can be
(a)20 ml (b)26 ml (c)15 ml (d) 30 ML

1there is a question in organic chemistry posted by srinath related to mechanism and i personally think more of targetiians trying that one that one is easy and conceptual so keep trying
33that will be good...
there are many errors today.. "error Day"
[3]
33Now got it..
[25,27]
[1]
I solved one in chemistry.. [1] although silly mol wt...[2]
62haha.. today we are finding each other's errors :P (how about a treaty not to :))))) ::))))
33;P
[2][2] thats my new mol wt of Ca(OH)2 ...
[2]
it is wrong [3]
that will be 57+17
33[7]
Let n gm of Na(OH) and 1-n gm of Ca(OH)2
then
n +2(1-n) = x
40 57 1000
and then 0≤n≤1
to get inequality in x
is it correct..
[7]
1priyam the range will be 25→27.027 so the only option satisfies is ..............
33@i mean think of it in terms of the range for the number of moles of (OH)!
[2]
I am getting then x as 24≤x≤35
not a fixed value and two options satisfies that..
[7]
1Who told u that??
It is not an equimolar mixture
The problem we are having is that 2 variables and one equation
62i mean think of it in terms of the range for the number of moles of (OH)!
3sir i cant get ur hint sir.wat means the possible combinations of NaOH and Ca(OH)2
62it is much simpler than this complex thinking...
Hint:
what will be the possible combinations of NaOH and Ca(OH)2
3sir i got the eqn
as meq of acid=meq of ca(oh)2+meq of NaOH
=3meq of NaOH
is it correct sir
1sorry bhaiyya i am so miserable in chemistry that i didn't even try this[2]
62arrey i meant that no one other than us is finding it any useful... :)
the answer is 26 isnt it?
62yup it is ..
and unfortunately only those of us who dotn need it are finding it of any use :D
