Question

Calculate the number of moles of sodium acetate added. Then calculate the hydrogen ion concentration from the pH. What are the possible sources of acetate ion? Are sodium salts soluble? Calculate the concentration of acetate ion from all sources in the solution. Finally, calculate the concentration of acetic acid in the solution after mixing in the sodium acetate. All these solutions contained 0.10 M acetic acid initially. Show your calculations. A suggested table might look like this: What is the relationship between acetic acid and sodium acetate? How are their formulas related? What general pattern(s) do you see in the data? Compare the relationship among the three concentrations. You can try multiplying all three or a combination of multiplying and dividing. Do the three sets of data give a constant or numbers that are similar? Is it similar to the relationship you found in Part II?

Explanation / Answer

First question Answer

Number of moles of sodium acetate added with 0.05 g= Mass/Molar mass

0.05/82

=6.09 * 10 ^-4

Number of moles of sodium acetate with 0.20 g

=0.20/82

=2.4 * 10 ^-3

pH=-log [H+]

[H+]=10 to power (-3.65)

[H+] =0.000224 mol/Litre

Most common source of acetate ions are any salt or ester of acetic acid.

Yes sodium ,potassium and ammonium salts are soluble in water.

Concentration of acetate ions from all sources ,For this one and last one we need the sources and their concentration (Whole experiment must be shared )
