- 5) Scientists use the pH scale to represent the level of acidity or alkalinity of a liquid. This is based on the molar concentration of hydronium ions, [H+]. Since the valu es of [H+] vary over a large range, 1 × 100 mole per liter to 1 x 10-14 mole per liter (mol/L), a logarith mic scale is used to compute the pH. The formula pH = -log[H+] represents the pH of a liquid as a function of its concentration of hydronium ions, [ H+]. The pH scale ranges from 0 to 14. Pure water is taken as neutral having a pH of 7. A pH less than 7 is acidic. A pH greater than 7 is alkaline (or basic). Two acids have [H+] valu es of 3.2 x 10-3 mol/L and 2.4 x 10-6 mol/L respectively. Find the pH for each acid. Which substance is more acidic? Round pH values to 1 decimal place.True or False: The concentration of iron (II) chloride ion in a solution that is incompletely labeled, [Cl-] = 4.0 M but made from iron (II) chloride is “2.0 M iron (II) chloride.”What reagent solution might you use to separate the cations in each of the following mixtures?

This is the net ionic equation I got, but I could easily be wrong: 2KBr(l) + 2FeCl3+(l) => 2FeCl2(s) + 2KCl(s) + I2(l) And Iton(III) chloride and potassium iodide: 2KI(s) + 2FeCl3(l) => 2FeCl2(s) + 2KCl(s) + I2(l) Write the four reduction reactions for Cl2, Br2, I2, and Fe3+ in order of easiest to reduce to hardest.In the laboratory you are given the task of separating Ca2+ and Ag* ions in aqueous solution.
