When mixing two liquids with different concentration percentages, what is the first step to find the required ratio?

  1. Calculate the volume of each liquid

  2. Determine the desired ultimate ratio by comparing concentration differences

  3. Assume equal parts of each liquid

  4. Measure the pH of each liquid

The correct answer is: Determine the desired ultimate ratio by comparing concentration differences

To find the required ratio when mixing two liquids with different concentration percentages, the first step is to determine the desired ultimate ratio by comparing concentration differences. This involves understanding the specific concentrations of both liquids and how they relate to the final desired mixture's concentration. By assessing the concentration of each liquid, you can establish a mathematical relationship that guides how much of each liquid should be mixed together to achieve the target concentration. This foundational step is crucial, as it informs the calculations that will follow, allowing for accurate mixing to reach the desired outcome. Calculating the volume of each liquid, assuming equal parts of each liquid, or measuring the pH are subsequent steps that may be necessary later, but establishing the concentration difference and the desired ratio is the essential first action that drives the entire mixing process.
