Back (Answer)

H + anything with H+ is usually acid!

#7
Front (Question)

Copper (II) ion

Back (Answer)

Cu 2+

#8
Front (Question)

Iron (II) ion

Back (Answer)

Fe 2+

#9
Front (Question)

Iron (III) ion

Back (Answer)

Fe 3+

#10
Front (Question)

ionic charge for group 1, 2, 13, 14, 15, 16, 17 and 18?

Back (Answer)

1 - 1+ 2 - 2+ 13 - 3+ 14 - 4+ 15 - 3- 16 - 2- 17 - 1- 18 - 0 (noble gas)

#11
Front (Question)

Hydrochloric Acid

Back (Answer)

HCl (0 charge)

#12
Front (Question)

Sodium Hydroxide

Back (Answer)

NaOH (0 charge)

#13
Front (Question)

Potassium Hydroxide

Back (Answer)

KOH (0 charge)

#14
Front (Question)

Calcium Hydroxide

Back (Answer)

Ca(OH)2 aka limewater

#15
Front (Question)

Sulfuric Acid

Back (Answer)

H2SO4 (0 charge)

#16
Front (Question)

Nitric Acid

Back (Answer)

HNO3

#17
Front (Question)

Acid-metal reaction?

Back (Answer)

acid + reactive metal → hydrogen gas (H2) + salt (remnants)

#18
Front (Question)

Acid-carbonate reaction?

Back (Answer)

acid + carbonate → carbon dioxide (CO2) + water (H2O) + salt (remnants) • when effervescence is observed / carbon dioxide is present, then it is an acid-carbonate reaction! carbonate = CO3 + smth

#19
Front (Question)

Acid-Alkali Reaction

Back (Answer)

Acid + Alkali → Water (H2O) + salt (remnants) • this is called neutralisation • no gas is produced!

#20
Front (Question)

Test for CO2

Back (Answer)

Bubble gas into limewater, a white precipitate will form if CO2 is present • for solid: odourless and colourless gas evolved • for liquid: effervescence of colourless and odourless gas observed • If CO2 is present, the reaction is an acid-carbonate reaction! (CO3 is one of the reactants)

#21
Front (Question)

Test for Hydrogen Gas (H2)

Back (Answer)

Hold lighted splint near edge of tube, the splint will extinguish with a ‘pop’ sound if hydrogen gas is present • If H2 is present, the reaction is a acid-metal reaction!

#22
Front (Question)

Zinc ion charge?

Back (Answer)

Zn 2+

#23
Front (Question)

Copper ion charge?

Back (Answer)

Copper (II) -> Cu 2+

#24
Front (Question)

Iron ion charge?

Back (Answer)

Iron (II) -> Fe 2+ Iron (III) -> Fe 3+
