Detecting presence of mercury ions in a sample of sugar in your house…
Since you don’t have test tubes, you may use a transparent glass.
Dissolve a sample of sugar (teaspoonful) in a quarter glassful of clean water (if you can get distilled water the better)
Prepare a separate solution of sodium chloride (a spoonful of common salt and quarter glass of water)
Add a few drops of the salt solution to the sugar solution…
Observation : if Hg²+ ions are present, the sugar solution will form a white precipitate (or become turbid or milky)
Copper (II) ions in sugar can be tested using wood ash solution where if present, a blue precipitate will be formed.
What’s Hg²+
And where can I find it?

Hg (hydrargyrum) is the chemical symbol for Mercury. So those are Mercury ions.
@fired thanks, this is very helpful.
Where’s Kebs while we are all trying to be scientists to escape consuming mercury?

-------------------->>>>>>>>Pale
hiyo white precipitate,is a sign of heavy metal yet to be confirmed in a bigger lab. stay tuned.

just tried this isht, no white precipitate observed.
Just tried for the sugar for Tomatoe sauce nikapata heavy pressence of Diethyl 2-bromoethylphosphonate with traces of Sodium Lauryl ether sulphate and minute presence of Gloco mono stearate. Naona Tomatoe sauce itakua thicker
