Determine the pH of solutions with the following ion concentrations:
1) {H+} = 1.0x10 to the negative 3 M
To determine the pH of a solution with a given concentration of H+ ions, you can use the equation for pH:
pH = -log[H+]
In this case, [H+] is given as 1.0x10^-3 M.
1) Convert the concentration of H+ ions from scientific notation to standard notation: 1.0x10^-3 = 0.001
2) Take the negative logarithm (base 10) of the H+ concentration: pH = -log(0.001)
3) Calculate the pH using a scientific calculator or by using logarithm properties:
pH = -log(0.001) = -(-3) = 3
Therefore, the pH of the solution with [H+] = 1.0x10^-3 M is 3.
