Reactions Of Metals And Metal Compounds Flashcards
What is aluminium used for?
Power lines because it is a good electricity conductor
Learn the metals song!!!
“Metals are shiny, metals conduct,
Metals are sonorous and malleable and ductile,
And metals have, And metals have, And metals have…
Generally high melting and boiling points!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!”
What are bridges made out of?
Iron and steel
What is gold used for?
Jewellery
What gas Is given off when metals react with acid?
Hydrogen gas
What salts are made when Hydrochloric acid is added?
Chlorides
What salt is made when sulphuric acid is used?
Sulphates
What salts are made when nitric acid is used?
Nitrates
What is the general equation for reacting metals with acid?
Acid + metal ➡️ salt + hydrogen
How do you test for hydrogen?
You put a burning splint inside a test tube of gas, and if hydrogen is present it will explode with a squeaky pop.
What are bases?
Bases are compounds which react with acids.
Name three types of bases
Metal oxides
Metal hydroxides
Metal carbonates
What are bases which dissolve in water called?
Give example
Alkalis
Sodium hydroxide
Give an example of the general equation for reacting acid and metal
Hydrochloric acid + zinc => zinc chloride + hydrogen
What happens when a metal oxide or hydroxide react with and acid?
Water and salt are formed and this process is called neutralisation.
What is the general equation for neutralisation?
Acid + metal oxide (or hydroxide) => salt + water
Name an example of neutralisation
Hydrochloric acid + potassium hydroxide => potassium chloride + water
How do you check for neutralisation?
Use universal indicator
Use litmus paper
See if the pH is 7 by seeing if it green
A metal carbonate will also __________________ an _____ and this time the products are ______ , _______________ and _________ .
Neutralise Acid Salt Carbon dioxide Water
What is the general equation for reacting metal carbonates and acids?
Acid + metal carbonate => salt + carbon dioxide + water
How can you test for carbon dioxide?
Use limewater
It will go milky and cloudy
Name a rock that contains calcium carbonate
Limestone
What happens when acid is added to a rock with calcium carbonate in it?
The rock fizzes and erodes which is called weathering.
What are the alkali metals??
Lithium Sodium Potassium Ceasium Rubidium
