If an aqueous solution has a pOH value of 10.7 and is at standard temperature and pressure, the pH value is 14 - 10.7 = 3.3. From the definition of pH, this means that the logarithm (to base 10) of the molar concentration of H+, [H+] is -3.3. This can be written as +0.7 - 4. The antilog of 0.7 is 5, to the justified number of significant digits. Therefore, [H+] = 5 X 10-4.

What is the mass number of an ion with 107 electrons 158 neutrons and a 1 charge?
The mass number of an ion is calculated by adding the number of protons and neutrons. Since the ion has 107 electrons and a charge of +1, it must have 108 protons (107 electrons + 1). Therefore, the mass number is 108 protons + 158 neutrons, which equals 266. Thus, the mass number of the ion is 266.
What is the pOH of a solution with (OH) 9.0 107?
To find the pOH of a solution, you can use the formula pOH = -log[OH⁻]. Given that the hydroxide ion concentration [OH⁻] is 9.0 × 10⁻⁷ M, the pOH can be calculated as follows: pOH = -log(9.0 × 10⁻⁷) ≈ 6.05. Thus, the pOH of the solution is approximately 6.05.
