# How to tell if it will neutralise? watch

1. This may seem a very obvious question, but I don't think I've been taught specifically how to tell.
Question:

Will 1 mol of HCl neutralise 5dm^3 of KOH of concentration 0.2mol/dm^3?

How would I go about working this out? We've been given a sheet of 24 of these types of questions to work out
It specifys calculators are not needed. Help please!

Thanks
2. Yes, it will exactly - 0.2mol/dm^3 just means that every dm^3 contains 0.2 mol of KOH, hence 5 dm^3 must contain 5 0.2 = 1 mol.
3. You write an equation between the acid and base, calculate Nm of H+ from acid and OH- from base, and compare it to the equation to see if all the moles of H+ and OH- react, thus becoming neutral.
4. so for the second one
Will 1 mol of HCl neutralise 2dm^3 of NaOH of concentrtation 0.2mol/dm^2?

That wouldn't neutralise it because 2 x 0.2 only = 0.4?
5. indeed isn't it?
