Individual Test

Question 1

Test For Carbonates

Answer 1

Add Carbonate to dilute Acid. Produces CO2+H20+Salt. It produces a gas that turns limewater milky as a white ppt forms

Question 2

Test for Carbonates Heat

Answer 2

When carbonates besides K/Na are heated they produce CO2

Question 3

Nitrates A

Answer 3

When dil h2SO4 ans FeSO4 is added to a test tube , then conc H2So4 without being shook a brown ring is formed which confirms the presence of a nitrate

Question 4

Nitrates B

Answer 4

When Nitrates minus K/Na are heated they produce NO2 and O2

Question 5

Nitrates C

Answer 5

This is detected by reducing the Nitrate into Ammonia. This is done by adding Al powder and NaOH under strong heating. If the gas produced turns red litmus blue (hence is ammonia gas) a nitrate is present

Question 6

Sulphates

Answer 6

Adding H2So4 followed by BaCl or BaNO3 results in a white ppt confirming presence

Question 7

Chloride

Answer 7

Adding H2SO4 followed by AgNO3 produces a white ppt to confirm presence
