This mindmap on Qualitative analysis contains the following content: -cation tests -anion test -solubility table I hope it helps :)
This mind map elaborates on content such as best practices, challenges, and examples. By interpreting their practical applications in various industries and fields, the map further showcases how they help businesses overcome obstacles and achieve success.
This mindmap is about Reproduction in flowering plants. It contains the following content: - characteristics of cross pollinated and wind pollinated flowers - advantages and disadvantages of self and cross pollination - functions of various parts in a monocotyledonous flower and what happens to those parts after fertilization - the process of pollination - the process of fertilization

Qualitative analysis
Cation tests
white precipitate
Aluminium
NH3
doesn't dissolve in excess ammonia
NaOH
dissolves in excess
Lead
Zinc
Calcium
Nh3
no precipitate is formed
doesn't dissolve in excess
colourful precipitates
Copper (Cu2+)
forms a light blue precipitate
dissolves in excess to form a deep blue solution
Iron (II) (Fe2+)
forms a green precipitate
Iron (III) (Fe3+)
forms a reddish brown precipitate
Anion Tests
test for anions
Carbonate (CO3 2-)
test
add dilute acid to substance
if effervescence is seen
test for carbon dioxide
buble the gas through limewater
if a white precipitate is formed, CO3 2- ions are present
Chloride (Cl-)
acidify with dilute nitric acid, then add AgNo3 (aq) OR PbNO3
result
white ppt of AgCl is formed
Iodide (I-)
yellow ppt of AgI formed
ppt of lead(II) iodide is formed
nitrate (NO3 2-)
make solution alkaline with aqueous sodium hydroxide then add aluminium foil; and warm carefully
ammonia gas given off
test for ammonia gas
place moist red litmus paper at the mouth of the test tube
if it turns blue, ammonia is present
Sulfate (SO4 2-)
Acidify with dilute HCl, then add BaCl (aq) or BaNO3 (aq)
white ppt of barium sulfate is formed
