5. Here is some information on four solid substances: Substance Calcium fluoride, CaF Potassium nitrate, KNO...
A solution contains 1.43×10-2 M ammonium fluoride and 6.08×10-3 M potassium sulfite. Solid calcium nitrate is added slowly to this mixture. A. What is the formula of the substance that precipitates first? B. What is the concentration of calcium ion when this precipitation first begins?
A) When aqueous solutions of potassium carbonate and calcium chloride are combined, solid calcium carbonate and a solution of potassium chloride are formed. The net ionic equation for this reaction is: B)When aqueous solutions of sodium acetate and hydrochloric acid are mixed, an aqueous solution of sodium chloride and acetic acid results. Write the net ionic equation for the reaction.Use H+ for the hydronium ion, CH3COOH for acetic acid and CH3COO- for the acetate ion. C)When solid Fe metal is...
Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms a product with chloride. Note that the formula of each product is determined by the charges of the ions,...
For questions 5-7, use the observations from the experiment to determine the names and formulas of various common compounds. 5. A common table salt substitute gives a lavender flame test. It also violds a nitric acid insoluble white precipitate upon the addition of silver nitrate. What are the formula and name of this compound sold salt substitute? Two of the ions in this lab depend on their conversion into a gas for detection. The two ions will forman ionic compound....
4.30. Using solubility rules, predict the solubility in water of the following ionic compounds. a. AI(OH) b. CaN C. NH4CI d. KOH 4.32. Using solubility rules, decide whether the following ionic solids are soluble or insoluble in water. If they are soluble, write the chemical equation for dissolving in water and indicate what ions you would expect to be present in solution. (NE SO b. BaCO c. Pb(NOs)2 d. Ca(OH) 4.34. Write net ionic equations for the following molecular equations....
could this experiment have been done in a different order? for
example, fe filing being removed at the end of the scheme. Why or
Why not?
Here is the procedure:
INTRODUCTION Most of the matter around us con combination of two or more Mixtures have the following fundamental proper natter around us consists of mixtures of different substances. A mixture results from the tivo or more pure substances, elements or compounds that do not react chemically. • Each component of...
Principles of Inorganic Chemistry! Week 5 Effect of Temperature on Solubility of a Salt In this experiment, you will study the effect of changing temperature on the amount of solute that will dissolve in a given amount of water. Water solubility is an important physical property in chemistry, and is often expressed as the mass of solute that dissolves in 100 g of water at a certain temperature. In this experiment, you will completely dissolve different quantities of potassium nitrate,...
