HgCl is the empirical formula of mercury I (mercurous) chloride, for which the full chemical formula is Hg2Cl2
The molecular formula of HgCl would be HgCl2. The molar mass of HgCl2 is approximately 472.2 g/mol, which corresponds to one mercury atom (Hg) and two chlorine atoms (Cl) in each molecule of mercury(II) chloride.
HgCl2 - mercury(II) chloride. Hg2Cl2 is mercury(I) chloride
The reaction is: Na2CO3 + 2HCl = 2NaCl + CO2 + H2O The net ionic is CO32- + 2 H+ = H2O + CO2
Since mercury can be either a 1+ ion called mercury(I), or a 2+ ion called mercury(II), there are two possibilities.Formulaspotassium chloride is KClpotassium iodide is KImercury(I) chloride is HgClmercury(I) iodide is HgImercury(II) chloride is HgCl2mercury(II) iodide is HgCl2Equation with Mercury(I)KCl + HgI --> HgCl + KIEquation with Mercury(II)2KCl + HgI2 --> HgCl2 + 2KI
To make a 0.01 M solution of HgCl, you need to know the molar mass of HgCl, which is 271.5 g/mol. With this information, you can calculate that 11.75 g of HgCl is equivalent to 0.0433 moles. For a 0.01 M solution, you would need 4.33 g of HgCl. Subtracting the initial 11.75 g, you find that 7.17 g of water is needed to make the solution.

To find the net ionic equation of the reaction between calcium chloride (CaCl₂) and mercury(II) nitrate (Hg(NO₃)₂), we start with the balanced equation: [ \text{CaCl}_2 (aq) + \text{Hg(NO}_3\text{)}_2 (aq) \rightarrow \text{Ca(NO}_3\text{)}_2 (aq) + 2 \text{HgCl}_2 (s) ] The complete ionic equation shows all soluble ions, and the net ionic equation focuses on the species that form the precipitate. The net ionic equation is: [ \text{Ca}^{2+} (aq) + 2 \text{Hg}^{2+} (aq) + 4 \text{Cl}^- (aq) \rightarrow \text{Ca}^{2+} (aq) + 2 \text{HgCl}_2 (s) ] After canceling spectator ions, the final net ionic equation is: [ 2 \text{Hg}^{2+} (aq) + 4 \text{Cl}^- (aq) \rightarrow 2 \text{HgCl}_2 (s) ]
A single mercurous ion has two positive charges and contains two mercury atoms and therefore has the formula Hg2+2. This cation requires two chloride anions, each which has a single negative charge, for the electroneutrality required in a compound between them, resulting in the formula given.
The reaction is: Na2CO3 + 2HCl = 2NaCl + CO2 + H2O The net ionic is CO32- + 2 H+ = H2O + CO2
To prepare Hager's reagent for alkaloid testing, dissolve 1 gram of mercuric chloride (HgCl₂) in 100 mL of distilled water. This solution can be used to precipitate alkaloids in plant extracts, forming a yellow precipitate that indicates the presence of alkaloids. Ensure to handle mercuric chloride with care, as it is toxic and hazardous. Store the prepared reagent in a dark glass bottle to protect it from light.
