1. What does 'the time taken to reach completion decreases if 20cm^3 of hcl containing 4mol/dm^3' means? How to work out to find the concentration?
2(a)What does concentrated hcl means?
(b)What does dilute hcl means?
Which will react faster or slower / a or b?
Thanks sooooo much !!
You need to clarify this post if you expect an answer. I have no idea what you're talking about.
