Oh no! Immediately after re-labelling the bottle of hydrochloric acid with the correct concentration, you find another unlabelled bottle in you lab! This bottle contains an aqeuous solution of sodium hydroxide which is again not labelled with the concentration. Using your pH probe, you measure the pH of the solution in the bottle as 13.53. From this, calculate the concentration of sodium hydroxide in the bottle (to 2 decimal places). Remember: pH = -log10[H3O+(aq)], pOH = -log10[OH-(aq)] and pH + pOH = 14.00

You are working in a chemistry laboratory when you come across a bottle which contains an aqueous solution of hydrochloric acid (HCl). Unfortunately, the person who prepared this solution was very sloppy and did not write down any details about the concentration of this solution! Luckily, you have a pH probe handy and you are able to measure the pH as 0.53. Using the value of pH that you measure, what is the concentration of the HCl solution (to 2 decimal places)? Remember: pH = -log10[H3O+(aq)]

A chemist dissolves 155.mg of pure hydrochloric acid in enough water to make up 270.mL of solution. Calculate the pH of the solution. Be sure your answer has the correct number of significant digits.

Hydrochloric acid (HCl) is commonly sold as a pool additive, where it is used to lower the pH of the pool water if it is too high. Swimming pools are commonly kept between a pH of 7.0 - 7.6 to ensure the comfort of the swimmers. You find a bottle of HCl in the pool aisle at the hardware store which is labelled as having a concentration of 192 g/L. What is the pH of this solution, to 2 decimal places? The molar mass of HCl is 36.46 g/mol.Remember: pH = -log10[H3O+(aq)], pOH = -log10[OH-(aq)] and pH + pOH = 14.00

The pH of a 0.001 M aqueous solution of sodium hydroxide will be:

200mL of 0.15 M HCl is added to 300mL of 0.090 M NaOH. What is the pH of the resulting solution?
