3. You will perform some calculations to see the difference between a pH buffer solution and a weak acid solution of the same pH when a small amount of strong base is added. Chlorous acid, HClO2, is a moderately strong acid with a Ka = 1.110×10-². Please answer the following questions. A. B. What is the molarity of the HClO2 solution whose pH is 2.38? M Please provider your answer below. 0₂ 3.76E-5 $ Check answer To prepare a buffer solution of the same pH, what is the molarity of the NaClO₂ if the molarity of the HClO2 is 0.6013 M? M Please provider your answer below.

You find a mysterious solution. You add universal indicator to it and the solution turns Yellow! What kind of solution is it and why?    A base, because it has a concentration of H+ ions less than 1 x 10^-7.   An acid, because it has a concentration of H+ ions less than 1 x 10^-7.   An acid, because it has a concentration of H+ ions greater than 1 x 10^-7.   A base, because it has a concentration of H+ ions greater than 1 x 10^-7

Weak bases Bases made with metal, dissociate and then combine with the hydre from water to create a weak acid, the metal ion and the hydroxide i a. These use a double-headed arrow F.

The pH solution ranges from 0 to 14. An acid has a pH less than 7. Pure water is neutral and has a pH of 7. The pH of a solution is given by pH=-logx where x represents the concentration of the hydrogen ions in the solution in moles per liter. Find the pH if the hydrogen ion concentration is 2.8x10-4.

Complete the table below identifying each unknown as an acid or base.    Unknown Solution Acid/Base Concentration (M) 0.01M NaOH     0.01M HCl     0.02M NaOH     0.02M HCl     0.04M NaOH     0.04M HCl     0.08M NaOH     0.08M HCl         If you mixed 30mL of 0.9M HCl with 45mL of DI water, what would the concentration be for the resulting solution?      What are the concentrations (in M) of Na+ ions and OH- ions within 1.30 liters of a 0.7M NaOH solution?      Given a 0.5M solution of HCl, calculate the [H3O+] and pH.      A solution has a pOH of 11. What is the [H+]?  Suppose you add 20 drops of 0.2M NaOH to 17 drops of 0.2M HCl. Phenolphthalein has been added tothe HCl. What color do you suspect the resulting solution will be? Why?   Assuming sulfuric acid completely dissociates in water, what are the concentrations of H+ and SO-42- in350mL of 0.25M H--2SO-4?

Prepare a written plan for making up 100.0 ml of 0.100 M Kl solution. Note the list of reagents and equipment provided in the background information. Include in your plan the exact amount of Kl that you will need and the actual steps that you will take to prepare the solution.
