Metals and acids year 11 chemistry

what is the pH scale and how do indicators work?

What are the physical properties of metals?

conduct electricity and heat

malleable

ductile

sonorous

high melting point

strong

How do metals react with oxygen?

booklet page 20 workbook page 17-19  

metals react with oxygen to form metal oxides

metal + oxygen --> metal oxide

How do metals react with water?

potassium - calcium react with water --> metal hydroxide + hydrogen gas

remaining metals react with steam only to form metal hydroxide + hydrogen gas

How do metals react with acids?

potassium, sodium and magnesium react violently with acids to form metal salts + hydrogen gas

Aluminium doesn't react with acids as it has an oxide layer

copper - platnium will not react with acids

How do metal carbonates react with acids?

metal carbonates + acid --> metal salt + water + carbon dioxide gas

How do different metals react?

Displacement reactions.

How can we change the rate of a chemical reaction?

surface area

temperature

concentration

catalyst

when graphing the rate, the steeper the line the faster the rate of reaction.

What is neutralisation?

when an acid and a base react together

neutralisation reactions

metal reactivity series

what are the uses of metals?
