Understanding the Problem
To solve the problem, we start with a mixture of acid and base in the ratio of 17:3. We need to determine how much of this mixture should be replaced with base such that the new ratio of acid to base becomes 1:1.
Initial Mixture Composition
- Let the total quantity of the mixture be 20 parts (17 parts acid + 3 parts base).
- Therefore, the initial amounts are:
- Acid = 17 parts
- Base = 3 parts
Let x be the fraction to be drawn off
- When we draw off x parts from the mixture, we remove:
- Acid removed = 17x/20
- Base removed = 3x/20
New Composition After Drawing Off x
- Remaining acid = 17 - (17x/20) = (340 - 17x)/20
- Remaining base = 3 - (3x/20) = (60 - 3x)/20
Substituting with Base
- After drawing off x parts, we add back x parts of base.
- New base amount = (60 - 3x)/20 + x = (60 - 3x + 20x)/20 = (60 + 17x)/20
Setting Up the Equation
- We want the new ratio of acid to base to be 1:1:
- (340 - 17x)/(60 + 17x) = 1
Solving the Equation
- Cross-multiplying gives us:
- 340 - 17x = 60 + 17x
- Rearranging yields: 280 = 34x
- Therefore, x = 280/34 = 40/5 = 8/5
Conclusion
To achieve a 1:1 ratio of acid and base, you must draw off 8/5 of the mixture and replace it entirely with base. Thus, the fraction of the mixture to be drawn off is 8/5 or 1.6 times the initial volume.
