PLEASE ANSWER!!! Sulfuric acid (a component of acid rain) reacts with limestone (calcium carbonate) to produce calcium sulfate a

nd carbon dioxide. This damages buildings and statues made of limestone. Which solution of sulfuric acid will damage these structures more quickly? A. 0.001% B. 0.005% C. 0.010% D. 0.015%

Answer:

The answer is D. 0.015%

Explanation:

That is the concentration of the Sulfuric Acid solution given in mass per mass percentage (w/w%), it means that the solution has 0.015 grams of Sulfuric Acid per 100 grams of solution. If it is compared with C answer, it has 0.005 grams more. Considering the reaction:

H_{2} SO_{4} + CaCO_{3} ⇒ CaSO_{4} + CO_{2} + H_{2}O

The more H_{2} SO_{4} (Sulfuric Acid) is present, the more CaCO_{3} (Limestone) is consumed.

Answer:

D is the best choice. Those percentages, are giving you the information about how concentrated are the solutions.  As 0.015 is so concentrated, this solution will damage the structures more quickly

calculate how much acid (acetic acid) and how much conjugate base (sodium acetate) must be used to make 500ml of a 0.8m acetate
kirza4 [7]

For the desired pH of 5.76, 0.365 mol of acetate and 0.035 mol of acid are to be added

let the concentration of acetate be x

then the concentration of acid will be (0.8 - x)

pKa of acetate buffer = 4.76

pH = pKa + log([acetate]/[acid])

⇒4.76 = 4.76 + log(x/(0.8-x))

⇒log(x/(0.8-x)) = 0

⇒x/(0.8-x) = 1

⇒x = 0.4

Therefore

[acetate] = x = 0.4

[acid] = 0.8-x =0.4 M

number of mol = concentration *(volume in mL)

number of mol of acetate = 0.4*0.5

= 0.20 mol

number of mol acid = 0.4*0.5

= 0.20 mol

when desired pH = 5.76

pH = pKa + log([acetate]/[acid])

⇒5.76 = 4.76 + log(x/(0.8-x))

⇒log(x/(0.8-x)) = 1

⇒x/(0.8-x) = 10

⇒x = 8 - 10x

⇒x = 8/11

⇒x= 0.73

[acetate] = x= 0.73

[acid] = 0.8-x = 0.07 M

number of mol = concentration * (volume in mL)

number of mol acetate to be added = 0.73*0.5 = 0.365 mol

number of mol acid to be added = 0.07*0.5 = 0.035 mol

Problem based on acetic acid required to maintain a certain pH
