A sample of 0.1687 g of an unknown monoprotic acid was dissolved in 25.0mL of water and titrated with 0.1150 M NaOH. The acid required 15.5mL of base to reach the equivalence point. (a) Explain what is the molecular weight of the acid? (b) After 7.25mL of base had been added in the titration, the pH was found to be 2.85. Explain what is the Ka for the unknown acid?
Which of the following is the correct pH of a 211.7 mL solution (final volume) of pure water after 52.3 mL of 1.00 mM HCl was added
The system then re-equilibrates. The appropriate chemical equation is PCl3+Cl2PCl5. Calculate the new partial pressures after equilibrium is re-established
Dry ice (solid ) has occasionally been used as an "explosive" in mining. A hole is drilled, dry ice and a small amount of gunpowder are placed in the hole, a fuse is added, and the hole is plugged.
