Think happy...thank God always...

God bless your home!

To Al candidate success and all the best. we believe you have adequately prepared yourselves

iis just 5weeks to start exams

 Hydrochloric acid is used to test Pb2+ Ag+ Co32- HCo3- SO32-
a)If added to a solution and white precipitate formed , either Pb2+ or Ag+ could be present when white precipitate dissolves on warming then Pb2+ confirmed

b) If added to either a solid or solution and there is effervescence /bubble of a colourless gas then either CO32- HCO3- or SO32- could be present.

 Potassium Iodide , a solid or solution used for confirming presence of Pb2+ by forming a deep yellow precipitate.
b) Iodide ions can also be oxidized by an oxidizing agent to iodine by changing to brown/black solution
 Barium nitrate identifies SO42- SO32- or CO32- by forming white precipitate
b) when HNO3 acid is added to the precipitate which doesn’t dissolve then confirms that the solution has a SO42-
c) If precipitate dissolves after adding the acid ,SO32- CO32- could be present
d) To confirm SO32- in (c ) above acidified orange dichromate turns from orange to green
it is being a reducing agent
 Dil. HCL or nitric acids can be used to dissolve basic oxides or hydroxides
 When a solid is heated and driplets of colourless liquid form on the cooler part
b) If blue litmus turn red and red remain re the acidic gas is evolved but if red litmus changes & blue remains blue the NH4+ is present
