An unknown amount of sodium hydroxide (FW= 40) was dissolved in 500 mL distilled water before standardized using 0.4928 g of potassium acid phthalate (MW = 204.23) in 75 mL distilled water. Calculate the unknown amount of sodium hydroxide in gram if the standardization needs 25.3 mL of sodium hydroxide to achieve the titration end point and the stoichiometric reaction between sodium hydroxide and potassium acid phthalate is one mole to one mole. (Note: FW = formula weight, MW = molecular weight)

Bay Water Titration The concentration of Cl- in ocean water is about 500-600 mM. The baywater is diluted by a factor of 12.5 using a 20.00 mL volumetric pipet and a 250 mL volumetric flask. Using a 15.00 mL volumetric pipet, 15.00 mL is transferred into three clean Erlenmeyer flasks. 10 mL of 1% dextrin solution, 20 mL of de-ionized water, and 3-4 drops of indicator are added and titrated each with the AgNO3 solution. From the procedure, find: Dilution factor Volume of diluted bay water Then calculate: The [Cl-] of diluted bay water The [Cl-] of bay water Consider this information: [AgNO3] = 0.04043177 trial # Veq 1 13.91 2 13.73 3 13.9 4 13.86 5 13.87 6 13.84 average 13.85167 [Cl-]Bay = ([AgNO3](Veq(ave))/Vdil bay water pipeted) (Vflask/Vbay water)
A 1.8M HCl solution was standardized against 1.4g sodium carbonate Na2CO3 (MW = 106g/mol) . The Na2CO3 standard required 13.5 mL of the HCl solution to completely react up to the indicator endpoint. Two chemists prepared their samples by taking 12.0-mL aliquots of each household ammonia solution and diluting it to 25.0 mL. With the same titrant and indicator, Chemist #1’s ammonia solution required 15 mL of the standardized titrant, whereas, Chemist #2's ammonia solution required 35 mL of the same titrant. Write the balanced equation for the analyte and the titrant Solve for the exact concentration of the HCl titrant in molarity.

If a student combines specific amount CaCl2. 9H2O and Na2CO3 and obtained a solid precipitate. The student dissolve 1.37 gram of CaCl2. 9H2O in 25.0 mL of water and 0.984 g of Na2CO3 in 25.0 mL of water. The student is then combining the two solutions and observed the formation of a solid precipitate. The student filter the solution and recovered the precipitate. The following data were obtained for the experiment. Initial Mass of CaCl2. 9H2O 1.37 g Initial Mass of Na2CO3 0.984 g % yield of this experiment 87.4% 1.

The two solids CuBr(s) and AgBr(s) are only very slightly soluble in water: Ksp(CuBr) = 4.2 × 10-8and Ksp(AgBr) = 7.7 × 10-13. Some CuBr(s) and AgBr(s) are both mixed into a quantity of water that is then stirred until it is saturated with respect to both solutes. Next, a small amount of KBr is added and dissolves completely. Compute the ratio of [Cu+] to [Ag+] after the system reestablishes equilibrium.
