What is the pH of a 0.25 M solution of HCLO4 (perchloric acid)?
How many grams of perchloric acid, HClO4, are contained in 31.3 g of 72.7 wt% aqueous perchloric acid? How many grams of water are in the same solution?
Determine the pH of the solution (to 2 decimal points) after the addition of 73.3 mL of 0.0154 M perchloric acid (HClO4) to 975 mL of 0.0517 M sodium hydrogen citrate (Na2C3H5O(COOH)(COO)2). Assume that the volumes are additive and that the 5% approximation is valid. A table of pKa values can be found here.
Determine the molality of 70.5% perchloric acid (HClO4)
A 0.4188-g sample of primary-standard Na2Co3 was treated with 39.50 mL of dilute perchloric acid. The solution was boiled to remove Co2 , following which the excess HclO4 was back-titrated with 9.35 mL of dilute NaOH . In a separate experiment, it was established that 26.75 mL of HCLO4 the neutralized the NaOH in a 25.00-mL portion. Calculate the molarities...
Calculate the pH at the equivalence point for the titration of 1.0 M ethylamine, C2H5NH2, by 1.0 M perchloric acid, HClO4. (pKb for C2H5NH2 = 3.25)
How many milliliters of 11.6 M perchloric acid solution should be used to prepare 1.50 L of 0.100 M HClO4?
Determine how many grams of indium perchlorate will be produced if 1.35 g of indium metal completely react with excess perchloric acid. Be sure to carefully balance the equation first. In(s) + HClO4(aq) ----> In(ClO4)3(aq) + H2(g)
When aqueous solutions of perchloric acid and calcium hydroxide are mixed, the following reaction occurs: 2HClO4 + Ca(OH)2Ca(ClO4)2 + 2 H2O If 32.9 mL of a 6.89×10-2 M Ca(OH)2 solution are required to react with 22.0 mL of HClO4 , what is the molarity of the HClO4 solution? Give your answer to three significant figures.
