The Ksp of Ag2CrO4 is 1.12× 10–12. ... Hydrogen sulfide gas is bubbled through a solution of potassium hydroxide. iron(II) chloride An alternative way to define the concentration of a solution is molality, abbreviated m. Molality is defined as the number of moles of solute in 1 kg of solvent. You are given a mixture of three solid compounds—A, B, and C—and are told that A is a polar compound, B is slightly polar, and C is nonpolar. \( H^+ + I^- + Cs^+ + OH^- \rightarrow Cs^+ + I^- + H_2O \). The temp is 25 degrees Celsius. Calcium hypochlorite [Ca(OCl)2] is an effective disinfectant for clothing and bedding. Write the molecular,complete ionic, and net ionic equations for the reactions that occur, if any, when solutions of the following substances are mixed: a) nitric acid and potassium carbonate b) sodium bromide and lead nitrate c), Al2(SO4)3+6KOH-->2Al(OH)3+3K2SO4 a)How many grams of potassium hydroxide are needed to completely react with 870 mg of aluminum sulfate? The other product is water. Predict whether each compound will dissolve in water and explain why. A 10.00 mL sample of a 1.07 M solution of potassium hydrogen phthalate (KHP, formula mass = 204.22 g/mol) is diluted to 250.0 mL. Why or why not? What is the concentration of the sulfide ion in solution after the precipitation reaction, assuming no further reaction? Why was it necessary to expand on the Arrhenius definition of an acid and a base? (Assume the density of the solution is 1.00 g/mL.). Which of the following is a strong electrolyte, a weak electrolyte, or a nonelectrolyte in aqueous solution? Aluminum sulfate reacts with calcium hydroxide (from lime) to form aluminum hydroxide and calcium sulfate. Type of reaction: Balanced Equation: 2) Hydrogen bromide, aluminum reacts with sulfuric acid to produce aluminum sulfate and hydrogen gas.

Like all alcohols, butanol contains an −OH group that can interact well with water. Predict whether mixing each pair of solutions will result in the formation of a precipitate. http://www.chem.vt.edu/RVGS/ACT/notes/solubility_rules.html. Why are many ionic substances soluble in water? Which graph corresponds to which titration? What would you suggest? Explain your answer. Write the acid name or chemical formula for each of the following: a.) Describe how you would prepare 500 mL of a 1.00 M stock solution of HCl from an HCl solution that is 12.11 M. Using your stock solution, how would you prepare 500 mL of a solution that is 0.012 M in HCl? If the calcium oxide were obtained by the heating of calcium hydroxide, how much hydroxide would be needed to obtain the 15.0 g? State whether each compound is an acid, a base, or a salt. What mass of precipitate would you expect to obtain by mixing 250 mL of a solution containing 4.88 g of Na2CrO4 with 200 mL of a solution containing 3.84 g of AgNO3? When potassium chloride is added to the solution, a precipitate forms. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. (Assume all the acidity is due to the presence of HCl.) barium hydroxide If the calcium oxide were obtained by the heating of calcium hydroxide, how much hydroxide … Chemistry. When potassium chloride is added to the solution, a precipitate forms.
