Sulfuric acid is a diprotic acid.    It's a two stages of ionization as shown below.               H2SO4  (aq)  →→  H+   + HSO4- (aq)    pKa  =  ???              HSO4- (aq)   ↔↔ H+    +  SO42-   pka  =  1.991                          a)   Calculate the concentration of HSO4-   &  SO42-  ion in a 0.5000 M  H2SO4 solution.            b)    Determine the pH of the solution to the correct number of significant figures. Q1A:   3.95 g NH4HCO3 is added to  1000 ml of water, What are the H3O+, OH-, NH3, and HCO3-?

Each value represents a different aqueous solution at 25 °C. Classify each solution as acidic, basic, or neutral. Acidic Basic Neutral pH = 3.53 pH = = 12.01 %3D [H* : = 1.1 × 10–6 H+] = 5.2 x 10-10 РОН 3D = 2.59 [OH] = 9.4 x 10-9 РОН 3D 12.04 [H* = 1.0 × 10-7 [OH] = 7.5 x 10-6 РОН — 7.00

Calculate the hydroxide ion concentration for a solution with [H3O+]eq = 2.8 × 10-5 M. Use "E" for scientific notation. i Respond with the correct number of significant figures in scientific notation (Use E notation and only 1 digit before decimal e.g. 2.5E5 for 2.5 x 105)

A solution has [H3O+] = 4.4×10−5 M . Use the ion product constant of water Kw=[H3O+][OH−] to find the [OH−] of the solution.   A solution has [OH−] = 2.5×10−2 M . Use the ion product constant of wate Kw=[H3O+][OH−] to find the [H3O+] of the solution.

Calculate the  [H3O+]  value of each aqueous solution. milk of magnesia with  [OH−]=1.2×10−5M  .Express your answer using two significant figures.

None

Calculate [OH-] given [H3O+] in each aqueous solution and classify the solution as acidic or basic. [H3O+] = 2.6 x 10-3 M [H3O+] = 2.6 x 10-8 M [H3O+] = 3.6 x 10-2 M [H3O+] = 4.3 x 10-3 M

Four solutions of an acid dissolved in water are sketched below, as if under a microscope so powerful individual atoms could be seen. The same volume of solution is shown in each sketch. Rank the solutions by the strength of the dissolved acid. That is, select 1 under the solution of the strongest acid, 2 under the solution of the next strongest acid, and so on. =H₂0 Note: Solution 1 (Choose one) Solution 3 (Choose one) Solution 2 (Choose one) Solution 4 (Choose one) X 5
