Analysis of silver mercury and lead lab

Group 1 cations includes those cations who selectively precipitates as chlorides by addition of diluted hydrochloric acid. These cations are respectevely: Ag+,Pb2+,Hg22+ . If we consider the whole periodic table, the only elements whose chlorides are insoluble are those of silver, lead (II) and mercury (I), Lab%2005%20%28-%29%20-%20Analysis%20of%20Silver%2c%20Mercury%20and%20Lead%20%28STUDENT%29 - Analysis of Silver Mercury and Lead Created by Jackie Silver, mercury(I) and lead(II) are often called the “chloride” group because they form sparingly soluble to insoluble precipitates with chloride ions. All three solids are white. The first step in isolating these ions from a solution is to add HCl to form the chloride precipitates.

Lead and mercury are naturally occurring elements in the earth's crust and are common environmental contaminants. Because people concerned about possible exposures to these elements often seek advice from their physicians, clinicians need to be aware of the signs and symptoms of lead and mercury poisoning, how to investigate a possible exposure and when intervention is necessary. SELECTING A METHOD FOR LEAD ANALYSIS The measurement of lead is based on similar chemistry to that which made lead so useful to humanity. There are many insoluble salts of lead, leading to the earliest known methods for determination of lead: precipitation based reactions. I was testing lead, silver, and mercury, When ammonia was added a white precipitate remained so I thought the answer was lead and mercury but that is not a choice. Lead and silver is a choice, but would the silver not have dissolved in ammonia? I know lead remained because it turned yellow when added the chromium.

QUALITATIVE ANALYSIS OF METAL CATIONS In the last post we studied the solubility product of salts and leant how we can manipulate the solubility of any salt by applying the common ion effect. In the coming Solubility product of Chlorides of lead, mercury and silver are lowest so they are precipitated first.

In this lab, we develop a scheme to separate and identify the silver ion (Ag +), the mercury(I) ion (Hg 2 2+), and the lead(II) ion (Pb 2+). Mercury(I) ions exist as dimers in aqueous solution, and function as a +2 ion. Qualitative Analysis- Group 1 Lab Questions. 1. Give the formula and colors for the chlorides formed with silver, lead and mercury(I). 2. Write a balanced net ionic equation for each of the following reactions: a. The precipatation of the chloride of Hg2 2+ in step 1. b. The formation of the yellow precipitate in Step 3. c.
