How to calculate pH of HCl in water?

What is my procedure in calculating the pH of a 0.1mol/l solution of NaCl? I found the pH of water, in an experiment to be 4.59. How do I use it in the a strong acid and strong base buffer, which I believe doesn't exist? i.e NaCl ---------------->...

What is the pH of a 0.240 molar HBr solution? Kw changes for a sample of water when there is a change in which of the following conditions? (Select all that apply.) 1 temperature [H+] [OH-] pressure What is the pH of a 0.058 molar Ba(OH)2 solution? What...

A solution is prepare by mixing 90.0 mL of 5.00 M HCL and 30.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+], [OH-], and the pH for this solution.

Calculate the pH when 0.5mL of 0.1M HCl is added to 30mL pure water.

For each of the following three questions 25.0 mL of 0.100 M pyridine (Kb = 1.70 x 10−9) is titrated with 0.100 M HCl. For each question calculate the pH of the final solution after the indicated amount of HCl has been added. That is, treat each...

Is this a trick question or am I missing something? 10^-6 moles of HCl gas is bubbled into a 10^6 L of pure water. What is the pH? It looks simple: 10^-6 mol / 10^6 L = 10^-12 M and then pH = -log(10^-12) = 12 But if you're adding an acid into pure water...
