when metal carbonates react with acids, what to they produce?
a salt + water + carbon dioxide
1 of 11
give the word equation for calcium carbonate reacting with hydrochloric acid
calcium carbonate + hydrochloric acid -> calcium chloride + water + carbon dioxide
2 of 11
Give a use for powdered limestone?
Powdered limestone can be used to raise the pH of acidic soils or lakes affected by acid rain
3 of 11
how does acid rain affect statues made out of limestone?
acid rain affects statutes because the calcium carbonate in the limestone reacts with the acids in the rain.
4 of 11
what is limestone aslo known as?
calcium hydroxide
5 of 11
describe a test that would show if carbon dioxide is present
put a few centimetres of limewater into a test tube, then get a straw and blow down the straw into a test tube and if the limewater turns cloudy that shows carbon dioxide present.
6 of 11
why does limewater go cloudy?
limewater goes couldy because insoluble calcium carbonate is produced
7 of 11
what happens when metal carbonate are heated?
when metal carbonates are heated they decompose to form a metal oxide and carbon dioxide
8 of 11
what is the order of the reactivity series
potassium, sodium, lithium, calcium, magnesium, aluminium, zinc, iron, tin, lead, copper, silver, gold.
9 of 11
what test could you use to test to see if hydrogen is present?
The squeeky pop test
10 of 11
how would you carry out the squeeky pop test?
soak a piece of wool in water, place it bottom of boiling tube with a piece of magnesium and a bung with a tube, hold finger over tube and heat boiling tube with bunsen burner, then remove finger from bung tube and place a lighted splint, if pop made
