1. A tank holds 90 L of chemical solution. Currently the solution has a strength of 20%. How much of this should be drained and replaced with an 80% solution to have a final strength of 30%?
Increasing solution strength to 30% refers to adding more of a solute (such as salt or sugar) to a given amount of solvent (such as water) to create a solution with a concentration of 30%. This means that for every 100 parts of the solution, 30 parts are the solute and 70 parts are the solvent.
Increasing solution strength to 30% may be desired for various reasons, such as to make the solution more effective in a particular application or to meet a specific requirement or target concentration.
The strength of a solution is typically measured in terms of its concentration, which is the amount of solute dissolved in a given amount of solvent. This can be expressed as a percentage, parts per million (ppm), or molarity (moles per liter).
The strength of a solution can be affected by various factors, including the amount of solute added, the temperature of the solution, and the type and purity of the solute and solvent used.
Not necessarily. The optimal solution strength will depend on the specific application and desired outcome. In some cases, a lower or higher concentration may be more effective or necessary.
