In what proportion should you combine 1:30 soaking solution and distilled water to create a 500ml solution of 1:70 concentration?
To determine the proportion of soaking solution and distilled water needed to create a 500ml solution of 1:70 concentration, we can use the concept of dilution.
The 1:70 concentration indicates that in a solution, there is 1 part of the solute (soaking solution) for every 70 parts of the solvent (distilled water).
In this case, the solute is the soaking solution, and the solvent is distilled water.
To determine the proportion, we need to find the ratio between the amount of solute (soaking solution) and the amount of solvent (distilled water) in the final solution.
Let's break down the process step by step:
Step 1: Calculate the total parts of the final solution.
- Since the concentration is given as a ratio of 1:70, the total parts would be 1+70 = 71.
Step 2: Determine the volume of the solute (soaking solution) required.
- Since the total volume of the final solution is 500ml, 1 part of the solute would be:
1/71 * 500ml = 7.04 ml (approx.)
Step 3: Calculate the volume of the solvent (distilled water) required.
- Since the total volume of the final solution is 500ml and the solute volume is 7.04ml, the solvent volume would be:
500ml - 7.04ml = 492.96 ml (approx.)
Therefore, to create a 500ml solution of 1:70 concentration, you would need to combine approximately 7.04 ml of the soaking solution and approximately 492.96 ml of distilled water.
