Calculate the pH and pOH of the solutions with the following hydrogen ion or hydroxide ion concentrations. Indicate which solutions are acidic, basic, or neutral. Complete parts 1-4 below. Part 1: [OH–] = 9.31×10-3M A: pH B: pOH Choose one: Acidic,Basic,Neutral Part 2: [OH–] = 5.49×10-9M A: pH B: pOH Choose one: Acidic,Basic,Neutral Part 3: [H+] = 4.93×10-8M A: pH B: pOH Choose one: Acidic,Basic,Neutral Part 4: [H+] = 4.15×10-4M A: pH B: pOH Choose one: Acidic,Basic,Neutral
The pH of a solution is the negative logarithm of the molar concentration of hydronium ion, that is, pH=−log[H3O+] In neutral solutions at 25 ∘C, [H3O+]=10−7 M and pH=7. As [H3O+] increases, pH decreases, so acidic solutions have a pH of less than 7. Basic solutions have a pH greater than 7. Calculate the pH of a 0.10 M solution of HCl. Express your answer numerically using two decimal places.
