Front (Question)

What ion causes a solution to be acidic?

Back (Answer)

Hydrogen

Front (Question)

What ion causes a solution to be alkaline?

Back (Answer)

Hydroxide ion

#10

Front (Question)

What makes an acid strong/weak?

Back (Answer)

Whether the acid molecules have dissociated to make ions (stronger) or not (weaker).

#11

Front (Question)

Define bases?

Back (Answer)

Bases are substances that can neutralise acids.

#12

Front (Question)

metal + acid → ?

Back (Answer)

Metal salt + hydrogen

#13

Front (Question)

Base (alkali) + acid → ?

Back (Answer)

Metal salt + water

#14

Front (Question)

Metal carbonate + acid → ?

Back (Answer)

Metal salt + water + carbon dioxide

#15

Front (Question)

Ammonia + acid → ?

Back (Answer)

Ammonium salts

#16

Front (Question)

What is the pH of acids

Back (Answer)

Below 7

#17

Front (Question)

What is the pH of alkalis?

Back (Answer)

Above 7

#18

Front (Question)

What are alkalis?

Back (Answer)

Soluble bases

#19

Front (Question)

What causes the pH of a solution to decrease by 1?

Back (Answer)

10 times more hydrogen ions

#20

Front (Question)

metal oxide + acid → ?

Back (Answer)

metal oxide + acid → salt + water

#21

Front (Question)

What would be done in order to create CuCl? (a soluable salt)

Back (Answer)

2HCL + CuO → CuCl2 +H2O

#22

Front (Question)

How could a soluble salt be created?

Back (Answer)

• reacting an acid with an insoluble salt • reacting an acid with an alkali

#23

Front (Question)

Why must a titration be used when reacting an acid and an alkali to form a soluble salt

Back (Answer)

A titration mus be used in order to see how much acid is needed to neutralise an alkaline solution- and vice-versa- therefore preventing the solution from becoming too acidic or alkaline.
