If a 25.0 mL sample of phosphoric acid, H3PO4, is completely neutralized by 137 mL of 0.100 M KOH, what is the molarity of the phosphoric acid? Given: H3PO4 + 3 KOH → 3 H2O + K3PO4
a) Calculate the final concentration when 25.0 mL of an 18.0 M HCl solution is diluted to 0.500 L. b) Calculate the volume required when an 8.50 M KOH solution is diluted to form 95.0 mL of a 0.500 M KOH solution
If a 25.0 mL solution of acetic acid of unknown concentration required 30.0 mL of 0.100M NaOH solution to be neutralized, what is the concentration of the unknown substance.
A 25.0 mL NaOH solution of unknown concentration was titrated with a 0.189 M HCl solution. 19.6 mL HCl was required to reach equivalence point. In a separate titration, a 10.0 mL H3PO4 solution was titrated with the same NaOH solution. This time, 34.9 mL NaOH was required to reach the equivalence point. What is the concentration of the H3PO4 solution?
Acid-base titration questions. Please help! Thanks. 2. Given that 20.00 mL of phosphoric acid solution required 15.50 mL of 0.200M NaOH for the first equivalent point. What is the molarity of the phosphoric acid? 3. A student titrated 25.00 mL of cola and it required 18.27 mL of 0.0100 M NaOH to reach the 1'equivalence point. Calculate the molar concentration of phosphoric acid in this brand of cola. 4. If the density of the "Cola" drink is 1.00 g/mL. What...
