1The flame test result for calcium is
- ALilac
- BGreen
- CBrick red
- DBlue
2The flame test result for Strontium
- ARed
- BBrick red
- CPale green
- DBlue
3The flame test result for Barium is
- ABrick red
- BLilac
- CPale green
- DBlue
4Group 2 hydroxide ions e.g. Mg(OH)2 increase in solubility down the group
- ATrue
- BFalse
5You can test for ammonia using damp [blank_start]red litmus paper[blank_end] - if ammonia is present the [blank_start]litmus paper[blank_end] will turn [blank_start]blue[blank_end]
- Ared litmus paper
- Blitmus paper
- Cblue
6To identify a sulfate ion, add dilute [blank_start]HCl[blank_end] and [blank_start]Barium chloride[blank_end] - if a [blank_start]white[blank_end] precipitate is formed then the original compound contained a sulfate
- AHCl
- BBarium chloride
- Cwhite
7Hydroxide ions (OH-) make [blank_start]alkaline[blank_end] solutions so pH indicator can be used to test it. Dip a piece of red [blank_start]litmus paper[blank_end] into the solution - if it turns [blank_start]blue[blank_end] then hydroxide ions are present
- Aalkaline
- Bacidic
- Cbasic
- Dlitmus paper
- Efilter paper
- Fblue
- Gred
- Hbrown
- Iyellow
8To test for the presence of halides (group 7), dilute [blank_start]nitric[blank_end] acid and silver nitrate can be added. AgCl gives a [blank_start]white[blank_end] precipitate, AgBr gives a [blank_start]cream[blank_end] precipitate and AgI gives a [blank_start]yellow[blank_end] precipitate
- Anitric
- Bhydrochloric
- Csulfuric
- Dwhite
- Ecream
- Fyellow
- Gcream
- Hyellow
- Iwhite
- Jyellow
- Kcream
- Lwhite
9Which of the following is insoluble in excess concentrated ammonia
- AAgCl
- BAgBr
- CAgI
- DAgF
10You can test for carbonate ions by reacting the solution with dilute HCl and then bubbling it through limewater. The limewater will turn cloudy if carbonate ions are present due to the CO2 being released
- ATrue
- BFalse
11The reducing power of halides decreases down the group
- ATrue
- BFalse
12The reducing power of halides [blank_start]increases[blank_end] down the group because the attraction between the nucleus and the outer electrons decreases as the size of the ions [blank_start]increase[blank_end] meaning the electrons are further from the nucleus and there is a greater shielding effect
- Aincreases
- Bincrease
13Halogens get less reactive down the group
- ATrue
- BFalse
14A halogen will displace a halide if it is [blank_start]below[blank_end] it on the periodic table
- Abelow
- Babove
- Cbeside
15Cl reacts with KBr to make an [blank_start]orange[blank_end] solution of Br2
- Aorange
16Br2 reacts with KI to make a [blank_start]brown[blank_end] solution of I2
- Abrown
17What colour and state is Fluorine
- APale yellow and gas
- BGreen and gas
- CRed-brown and liquid
- DGrey and solid
18What colour and state is chlorine
- APale yellow and gas
- BGreen and gas
- CRed-brown and liquid
- DGrey and solid
19What colour and state is bromine
- APale yellow and gas
- BGreen and gas
- CRed-brown and liquid
- DGrey and solid
20What colour and state is iodine
- APale yellow and gas
- BGreen and gas
- CRed-brown and liquid
- DGrey and solid
