In a neutralisation reaction, an acid reacts with an alkali, what are the two products?
Salt and Water
Lithium Hydroxide + Hydrochloric Acid -> ??
Lithium Chloride + Water

Why are indicators useful?
They change different colours at different pH levels
name 1 advantage of universal indicator over litmus indicator
it can tell you the strength of the pH / solution
what does filtration separate?
