Hayem's solution. This is an isotonic fluid which consists of the folIowing constituents (in g/100 ml):sodium chloride 0.5, sodium sulphate 2.5 and mercuric chloride 0.25. The sodium sulphate discourages clumping of the erythrocytes and the mercuric chloride is a preservative.
hayem solution contains: sodium chloride 0.5%, sodium sulphate 2.5% and mercuric chloride 0.25%. The sodium sulphate discourages clumping of the erythrocytes and the mercuric chloride is a preservation
when we heat the mercuric oxide in the test tube the mercuric oxide returns to a black color when we get out on the flame they will be back on the normal
formaldehyde reacts with oxidised indole ring to give coloured complex .mercuric sulphate in sulphuric acid acts as the oxidising agent
by heating mercuric oxide oxygen will evaporate and mercury will be left in the flask
Mercuric oxide is in the solid state.
HgO, this is formula for mercuric oxide.
Hayem's solution contain Mercuric chloride, sodium sulphate, sodium chloride and distilled water. It dissolves WBCs, dilutes RBCs and provides an isotonic environment for RBCs.
Mercuric or mercury II chloride is HgCl2
Mercuric oxide or mercury (II) oxide : HgO
the colour of mercuric oxide is an orange powder.
