15.32. 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. a. [OH-] = 7.69 X 10 M b. [OH-] = 2.18 x 10-'M c. [H-] = 4.0 x 10-8 M d. [H+] = 3.56 X 10-4 M
Calculate the pH and pOH of the solutions with the following hydronium ion [H3O+] or hydroxide ion [OH–] concentrations. Determine which solutions are acidic, basic or neutral. (1.a) [OH–] = 8.2 × 10–11 M (1.b) [OH–] = 7.7 × 10–6 M (1.c) [H3O+] = 3.2 × 10–4 M (1.d) [H3O+] = 1.0 × 10–7 M
Typically the concentration of hydronium, H3O+, or hydroxide, OH−, ions in an aqueous solution is less than 1 M. It is not uncommon to have hydronium ion concentrations that are much smaller, such as 2.60×10−5. pH, therefore, is a convenient way to restate the hydronium concentration. pH is equal to the negative log of a hydronium ion concentration in solution: pH=−log[H3O+] Access the pH calculation simulation, which will open in a new window. Edit the concentration by typing a value...
What is the total concentration of all ions (the sum of their individual concentrations) in aqueous solutions of the following? Hint: Each substance is an electrolyte that dissociates in water to produce ions. Use the link table of polyatomic ions if you do not recognize the polyatomic ion. For example, Na2SO4->2Na1++ SO,2- when it dissolves, so a 1 M soln of Na,SO4 is 2M in Na1 and 1M in so2- and the total concentration of ions is 2 M 1...
When solutions of acetic acid and magnesium hydroxide react, which of the following are spectator ions? A) hydrogen ion B) acetate ion C) magnesium ion D) hydroxide ion E) none of these
2. What is the total concentration of all ions (the sum of their individual concentrations) in aqueous solutions of the following? Hint: Each substance is an electrolyte that dissociates in water to produce ions. Use the link table of polyatomic ions if you do not recognize the polyatomic ion. For example, Na2SO4 -> 2Na1+ + SO42- when it dissolves, so a 1 M soln of Na2SO4 is 2M in Na1+ and 1M in SO42- and the total concentration of ions...
