18. A beverage mixture contains citric acid, C6H8O7 (molar mass 192 g/mol), plus sugar and flavorings. The mass of citric acid in a sample was determined by titration with sodium hydroxide solution.

(Citric acid has three dissociable protons) A) 4.98 g B) 1.11 g C) 0.956 g D) 0.319 g E) None of these is correct
A 1.50 g sample of KCl is dissolved in 36.0 mL of water. The resulting solution is then added to 32.0 mL of a 0.470 M CaCl2 (aq) solution. Assuming that the volumes are additive, calculate the concentrations of each ion present in the final solution. Concentration of K* ions = M Concentration of Ca2+ ions = M Concentration of Cl ions = M
Suppose 31.0 mL of 0.510 M CoCl2 solution is added to 72.0 mL of 0.180 M NiCl2 solution. Calculate the concentration, in moles per liter, of each of the ions present after mixing. Assume that the volumes are additive. Concentration of Co2+ = mol/L Concentration of Ni2+= mol/L Concentration of Cl- = mol/L
A student mixes 100.0 mL of 0.500 M AgNO3 with 100.0 mL of 0.500 M CaCl2. Write the balanced molecular equation for the reaction. Write the net ionic equation for the reaction. How many grams of precipitate will form? What is the concentration of Ag+, NO3‒, Ca2+, and Cl‒ in the final solution (assume volumes are additive).
In the laboratory you are given the task of separating Ca2+ and Fe2+ ions in aqueous solution. For each reagent listed below indicate if it can be used to separate the ions. Type "Y" for yes or "N" for no. If the reagent CAN be used to separate the lons, give the formula of the precipitate. If it cannot, type "No" Y or N 1. 12. 3 Reagent Formula of Precipitate if YES ка K₂SO4 Na CO
A titration is performed to determine the amount of sulfuric acid, H2SO4,, in a 6.5mL sample taken from a car battery. About 50mL of water is added to the sample, and then it is titrated with 43.37mL of standard 0.5824 molar NaOH solution. How many moles of sulfuric acid are present in the original sample?
10) A beaker contains 0.300 L of a 0.20 M Pb(NO3)2 solution. If 0.200 L of a 0.20 M solution of MgCl2 is added to the beaker, what will be the final excess moles of Pb^+2 ions in the resulting solution?
3. A 2.315 g sample of H2C2O4•2H2O was transferred to a 100.0-mL volumetric flask and diluted to the mark. 20.00 mL of this solution required 26.37 mL of a NaOH solution of unknown concentration to reach the end point. Calculate the molarity of the NaOH solution. PE40
Aluminum ions may be precipitated from aqueous solution by the addition of hydroxide ion, forming Al(OH)3. A large excess of hydroxide ion must not be added, however, because the precipitate of Al(OH)3 will redissolve as a soluble compound containing aluminum ions, and hydroxide ions begin to form. How many grams of solid NaOH should be added to 10.1 mL of 0.107 M AIC13 to just precipitate all the aluminum? g
Hydrochloric acid, HCl, and calcium hydroxide, Ca(OH)2, react with each other in a neutralization reaction. Suppose that 0.28 mL of 42.3 M HCl solution is needed to neutralize an aqueous solution of Ca(OH)2. How many grams of Ca(OH)2 must be dissolved in the solution? The molar mass of Ca(OH)2 is 74.10 g/mol.
