2.) Vinegar is an aqueous solution (homogenous mixture) of acetic acid and water (aqueous="aqua"= Latin for water). To simplify the calculations let us assume that all of the acetic acid in the vinegar reacts and there is some left over "excess" baking soda. The vinegar solution is a 5% acetic acid solution. If you look at the bottle of vinegar somewhere on there it probably says "5% acidity" or similar notation. Let us estimate that about 25.0 g of vinegar...

The pH of a vinegar (acetic acid) solution is 5.25. How many grams of acetic acid are needed in one liter of solution to give the same pH?
A student is trying to determine the concentration of an acetic acid (HC2H3O2) solution. They place 5.00 mL of it in a flask and titrate it with a 0.150 M NaOH solution. At the endpoint of the titration, they find that they have used 19.27 mL of the NaOH solution. Based on this information answer the following questions. a) How many moles of NaOH are used to reach the endpoint? ____moles NaOH b) How many moles of acetic acid were...
2) 19.63 mL of 0.100 M NaOH is required to neutralize 2.00 mL of a solution containing acetic acid according to the following reaction: HC2H302(aq) + NaOH(aq) → NaC2H3O2(aq) + H2O(1). How many grams of acetic acid are present in 2 mL solution? Report the correct number of significant figures, and report the units. 3) 19.63 mL of 0.100 M NaOH is required to neutralize 2.00 mL of a solution containing acetic acid according to the following reaction: HC2H3O2(aq) +...
Calculate the pH of an aqueous acetic acid (HC2H3O2) solution that is 18.0 % acetic acid by mass. The Ka of acetic acid = 1.75 x 10−5 . Assume the density of the solution to be 1.03 g/ml.
4. A solution is made by dissolving 15.00 grams of acetic acid and 3.25 grams of sodium acetate in 500.00 mL of water. What is the pH of the solution? The K, of acetic acid is 1.8 x 10. (Hints: First convert grams to mol and then determine the molarity of acetic acid and sodium acetate, ...) 5. What is the pH of a 2.50 molar solution of NHCl(aq)? The Ko for NH, is 1.8 x 105. 6. A certain...
How many grams of acetic acid are in a sample solution if 22.50 mL of a 0.125 M sodium hydroxide solution are required to neutralize it?
Vinegar is a solution of acetic acid. Acetic acid has a 1:1 ratio when reacted with NaOH. a. Suppose that the molarity of acetic acid in vinegar is 0.5 M, how many grams of acetic acid are present in the 5 ml of vinegar solution used in the titration? (molar mass of acetic acid = 60 g/mol). b. If vinegar has a density of 1.01 g/mol. Calculate the % of acetic acid in vinegar by mass.
