Answer:
A) solution 2 is more acidic than solution 1
B) Graph in attachment
C) Ratio method prefer
Explanation:
A chemist prepares two acid solutions.
Solution 1: 3 parts sulfuric acid to 7 parts water
Ratio of sulphur to water
![=(3)/(7)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/at14ngzns7f21t33f4thlfhjqo3jaoqcst.png)
Solution 2: 4 parts sulfuric acid to 9 parts water
Ratio of sulphur to water
![=(4)/(9)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/hwlk7bywnbfwshlhy6ecxq1rnlq985augi.png)
Part A: Using ratio to find the more acidic
First we make same denominator
Solution 1:
![\Rightarrow (3* 9)/(7* 9)=(27)/(63)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/mg650snlcmljilwqon7glskp7qvt23ebod.png)
Solution 2:
![\Rightarrow (4* 7)/(9* 7)=(28)/(63)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/prmj8mswg2pympfcb2fhqkgiukbu9icfsn.png)
As 28 > 27
Therefore, solution 2 is more acidic than solution 1
Part B: Let y amount of sulfuric acid mix with x amount of water.
Equation of solution 1:
![y=(3)/(7)x](https://img.qammunity.org/2019/formulas/mathematics/middle-school/kfzjzzz2o5ele7kg172dq9srgi7b3kcx3a.png)
Equation of solution 2:
![y=(4)/(9)x](https://img.qammunity.org/2019/formulas/mathematics/middle-school/j2ihhr2tys8pbgcp8qhw31qjwx1jnfnja7.png)
Please find attachment for graph.
Part C: part A method is more prefer to find more acidic. Because it gives actual amount of acidic.
