What is an Alkalai
A base that dissolves in water
A base that is not soluble
An acid that corrodes the skin
A base that will react explosively with an acid
Which of the following is true?
If a substance has a pH of 0+ then it is Acidic
If a Substance Has a pH of 0- then it is Acidic
If a Substance has a pH of below 3 then it is Acidic
If a Substance has a pH of below 7 then it is Acidic
What colour will a neutral solution turn Universal indicator paper

When acids dissolve in water, what do they produce?
aqueous hydrogen ions, H+(aq)
aqueous hydroxide ions, OH–(aq)
aqueous Chlorine ions, Cl+(ag)
aqueous Sulfate ions, S-(aq)
What do Alkalies produce when dissolved in water?
aqueous Hydroxide ions, OH-,(aq)
aqueous Hydrogen ions, H+,(aq)
aqueous Chlorine ions, Cl-, (aq)
aqueous Sulfur ions, S+, (aq)
Which is the correct equation for the Neutralisation reaction
H+(aq) + OH–(aq) → H2O(l)
H+(aq) + H2O(l) → OH-(aq)
H+(aq) + OH-(aq) = Cl-(l)
H+(ag) + Cl-(aq) = H2O(I)
When a Acid and base react, what is the result product?
Chlorine + Water
Salt + Chlorine
Salt + Water
Chlorine + Salt
