Question

QUESTION 4 If you find that you need an acid to base ratio of 4.23 and you are using 50.00mL of a 1.00M acid solution, what volume of 1.00M base solution should you use?

a) 212 mL

b) 32.6 mL

c) 85.9 mL

d) 11.8 mL

Answer 1

Ans. Given data- Ratio of millimoles of acid to base = 4.23 rie. Millimoles of acid 4.23 O Millimoles of base Calculate the milli moles of acid Millimoles of awd = Molasu'ty x volume Cin mu) = IMX 50 ml 50 50 milli moles Millimoles of base = molarity x volume Cin mi) – ☺ Put the millimoles of acid in equation ③ - = 4.93 Mollimoles of bose Millmoles of base = 50 = 11.8 millimoles Put this value in equation ③ Volume of base = millimoles of base = 11.8 Molarity | volume of base = 11.8 ml Correct option is @ 4.23 Cin mL)
