Suppose that you have a solution that is 1.0 g/L Ca(OH)2 and you want to prepare...
A solution is prepared by dissolving 0.0034 g Ca(OH)2 in enough water to prepare a 250 mL solution. what is the pH of the solution if Ca(OH)2 completely dissociates producing 2 OH for every 1 Ca
You want to prepare 1.0 L of a 0.15 M NaCl solution in DI water. Show the calculations needed to prepare this solution and explain the steps you would need to take to prepare it using the solid crystal NaCl and DI water. The molecular weight of NaCl is 58.44 g/mol.
Suppose a student titrates a 10.00-mL aliquot of saturated Ca(OH)2 solution to the equivalence point with 14.30 mL of 0.0224 M HCl. What was the initial [OH − ]? WebAssign will check your answer for the correct number of significant figures .064 M 1 Incorrect: Your answer is incorrect. What is the experimental value of Ksp?
When preparing 150.0 mL of a 0.250 M solution of Ca(OH)2 from a 4.9 M stock solution how much of the stock solution (in mL) do you need to add? Record to the appropriate amount of significant figures.
Review Problem 16.066 A solution was made by dissolving 0.818 g Ca(OH)2 in 100 ml final volume. (Note: For the purpose of significant figures, assume Kw - 1.00 x 10" (a) What is the molar concentration of OH" in the solution? (OH) - (b) What is the pH? pH- (c) What is the pOH? рон (d) What is the hydrogen ion concentration in the solution? (H) - Click if you would like to Show Work for this question: Open Show...
you add an excess of ca(oh)2 to water maintained at particular temperature, stir until the solution is saturated, filter, then determine the OH in the solution by titration with acid. titration of 10.0 ml of the calcium hydroxide solution to the end point requires 4.86 ml of 0.070 M HCl solution. what is the molar quantity of OH- in the 10.0 ml of solution? what are the concentrations of Ca2+ and OH- ? WHAT IS THE SOLUBILITY OF Ca(OH)2 under...
A 2.5×10−2 M solution of HCl is used to titrate 147 mL of a Ca(OH)2 solution of unknown concentration. 1. If 100 mL of HCl is required, what is the normality of the Ca(OH)2 solution? Express your answer using two significant figures. 2. What is the molarity? Express your answer using two significant figures.
answer (2) 2. Suppose that you used a known concentration (0.8442 M) of Ca(OH)2 to determine the concentration of an unknown HBr solution. If it takes 12.88 mL of the Ca(OH)2 solution to titrate 15.00 mL of the unknown HBr solution, what is the molarity of the HBr? 1. A solid diprotic weak acid, H2A (molecular weight = 128.9 g/mol) is used to standardize a KOH solution. When 0.4228 g of the acid is dissolved in 40.0 mL of water...
if you have 6.72 g of mg(oh)2 what would the molar concentration of a solution be if you dissolved the mg(oh)2 in 432 ml of water
1. In the lab, you will prepare a 1.0 L, 0.10 M ammonium chloride solution using a 1.0 M ammonium chloride stock solution. How much of the stock solution will be used to prepare the diluted, 0.10 M solution? Report your answer with 1 significant figure in mL. Do not include units in your answer and do not type your answer in scientific notation. 2. In the lab, you will prepare a 1.0 L, 0.10 M acetic acid solution using...
