A compound produced from the reaction between two substances (one solid and the other was gas ) and burns in air with a brilliant white flame, this is a qualitative reaction. *

Determine the copper 2 chloride in the original sample

Six aqueous solutions were used in a series of solubility experiments.  Each solution was mixed with each of the other five according to the table below.  The observations of each mixture are written in the appropriate box.  What is the chemical formula of the precipitate formed when magnesium sulfate is mixed with strontium chloride?   Write the formula equation for the reaction between sodium sulfate and strontium chloride.

One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. Suppose an EPA chemist tests a 200. mL sample of groundwater known to be contaminated with tin(II) chloride, which would react with silver nitrate solution like this: SnCl,(aq) + 2 AgNO3(aq) → 2 AgCl(s) + Sn(NO,),(aq) 2 The chemist adds 77.0 mM silver nitrate solution to the sample until silver chloride stops forming. He then washes, dries, and weighs the precipitate. He finds he has collected 3.3 mg of silver chloride. Calculate the concentration of tin(II) chloride contaminant in the original groundwater sample. Be sure your answer has the correct number of significant digits. mg x10 Submit Assignmen Continue O2020 McGraw-Hill Education. All Rights Reserved.
