Question

A chemist prepares two acid solutions.

Solution 1
3 parts sulfuric acid to 7 parts water

Solution 2
4 parts sulfuric acid to 9 parts water

a. Use a ratio table to determine which solution is more acidic.

Question 2
Solution
has the greater concentration.

Question 3
b. Use a graph to determine which solution is more acidic.
Put responses in the correct input to answer the question. Select a response, navigate to the desired input and insert the response. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse.
Both graphs begin at $($ Response area, Response area $)$ . The graph for solution Response area is steeper, so it has Response area concentration of acid.

Answer 1

A) solution 2 is more acidic than solution 1

Explanation:

A chemist prepares two acid solutions:

Solution 1: 3 parts sulfuric acid to 7 parts water

Ratio of sulphur to water: 3/7 (3:7)

Solution 2: 4 parts sulfuric acid to 9 parts water

Ratio of sulphur to water: 4/9 (4:9)

___________________________________________________

Part A: (using ratios to determine which solution is more acidic)

First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.

Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63

Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63

Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.

Mathematical Line (Not sure what you would call this lol): 28 > 27

Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)

Equation of solution 1: y = 3/7x

Equation of solution 2: y = 4/9x

Please find attachment for graph.

Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)
