#1
Front (Question)

What do acids contain

Back (Answer)

H+ ions

#2
Front (Question)

Strong acids…

Back (Answer)

… release all its hydrogen atoms into solution as H+ ions and completely dissociates in aqueous solution

#3
Front (Question)

Weak acids…

Back (Answer)

… release only a small proportion of its available hydrogen atoms into solution as H+ ions and only partially dissociates in aqueous solution

#4
Front (Question)

What does the equilibrium ⇌ sign indicate

Back (Answer)

That the forward reaction is incomplete

#5
Front (Question)

Generally, what acids are weak acids?

Back (Answer)

Organic acids such as ethanoic acid

#6
Front (Question)

Examples of bases

Back (Answer)

Metal oxides, metal hydroxides, metal carbonates and ammonia

#7
Front (Question)

What is a base

Back (Answer)

Neutralises an acid to form a salt

#8
Front (Question)

What is an alkali

Back (Answer)

A base that dissolves in water releasing hydroxide ions (OH-) into the solution

#9
Front (Question)

What happens in neutralisation of an acid with metal oxides or hydroxides

Back (Answer)

H+ ions react with a base to form a salt and neutral water

#10
Front (Question)

Acid + Alkali ->

Back (Answer)

Salt + Water

#11
Front (Question)

Full and Ionic Equation of Hydrochloric acid and Sodium hydroxide (NaOH)

Back (Answer)

Full Equation: HCl + NaOH -> NaCl + H2O Ionic Equation: H+ + OH- -> H2O

#12
Front (Question)

What happens in neutralisation of acids with carbonates

Back (Answer)

Forms a salt, water and carbon dioxide
