Answer:
[tex]\large \boxed{\text{Q5. 20.2 mL; Q6. 9.8 mL; Q7. Yes}}[/tex]
Step-by-step explanation:
Question 5
You have a 50 % (1:1) syrup and a 1:200 (0.5 %) soda solution and you want to make a 1:6 (16.67 %) final solution.
Let x = the volume of 1:200 (0.5 %) soda solution.
Then 30 - x = the volume of the 1:1 (50 %) syrup solution
[tex]\begin{array}{rcl}\text{syrup in } 0.5 \% + \text{syrup in } 50 \% & = & \text{syrup in} 16.67 \%\\0.5x + 50(30 - x)& = & 30\times 16.67\\0.5x + 1500 - 50x& = & 500\\1500 - 49.5x& = & 500\\49.5x& = & 1000\\x& = & \dfrac{1000}{49.5}\\x& = & \textbf{20.2 mL}\\\end{array}\\\text{The volume of soda solution required is $\large \boxed{\textbf{20.2 mL}}$}[/tex]
Question 6
Volume of solution 1:6 solution = 30 mL
-Less volume of 0.5 % soda = 20.2 mL
Volume of 50 % syrup = 9.8 mL
Question 7
Yes.
The two liquids should be miscible or form an emulsion that is stable enough that the patient can get the right proportion of the ingredients, "Shake well before taking".
Question 8
A. Alligation alternate is used to find the amount of each ingredient needed to make a given quantity of a mixture.
B. Alligation medial is used to find the amount of a mixture given the quantities of its ingredients.
