Question

How many liters of 1.5 M HCl solution would react completely with 6.5 moles Ca(OH)2?

Answer 1

Did u work this out ?

Answer 2

I don't know how :/

Answer 3

The 1st thing we have to do here is to balance the chemical reaction of these 2

Answer 4

The 1st thing we have to do here is to balance the chemical reaction of these 2\[Ca(OH)_{2} + 2HCl \rightarrow CaCl _{_{2}} + 2H _{2}O\]

Answer 5

So according to the equation we can see 1 mole of Ca(OH)2 reacts with 2 moles of HCl right?

Answer 6

Yes

Answer 7

That means 6.5 moles of Ca(OH)2 will react with 13 moles of HCl right

Answer 8

Yeah

Answer 9

so now we know the no of moles and the concentration of HCl
Now use n=C x V

Answer 10

so V= n divided by C

Answer 11

Ohh ok

Answer 12

So what I got was 8.66 L ? Just double check the answer ! I hope you got it ?!

Answer 13

I did! Thanks :)

Answer 14

welcome !
