Strength stock solution
A dilution is a solution made by adding more solvent to a more concentrated solution (stock solution), which reduces the concentration of the solute.An example of a dilute solution is tap water, which is mostly water (solvent), with a small amount of dissolved minerals and gasses (solutes). When making up stock solutions, the strength of the reagent is often overlooked. If the reagent is less than 100% strength i.e. less than 100% of the mass is the actual reagent (the remainder being impurities), it will normally be stated by the manufacturer on the container and you should take this into account when calculating how much of it Similarly for a percentage stock strength solution the equation will be as in the following example. ExampleCalculate the amount of (i) stock solution required, and (ii) water required to make 0.4 litre of 1% solution from 2% Stock Strength. Amount of stock required = Strength Required Stock Strength ×Volume Required = 1/100 2/100 × 0.4 = 0 stock solution A solution of a known concentration prepared for the convenience of dispensing; usually a strong solution from which weaker ones can be made conveniently. Stock solutions usually are prepared on a weight-in-volume basis, and their concentration is expressed as a ratio strength or less frequently as a percentage strength. Real-life chemists in real-life labs don’t make every solution from scratch. Instead, they make concentrated stock solutions and then make dilutions of those stocks as necessary for a given experiment. To make a dilution, you simply add a small quantity of a concentrated stock solution to an amount of pure solvent. The resulting solution contains …
Similarly for a percentage stock strength solution the equation will be as in the following example. ExampleCalculate the amount of (i) stock solution required, and (ii) water required to make 0.4 litre of 1% solution from 2% Stock Strength. Amount of stock required = Strength Required Stock Strength ×Volume Required = 1/100 2/100 × 0.4 = 0

A normal working solution is a 1x, or normal strength solution. A Stock solution as a component of a complex working solution . A stock solution can be mixed along with other components, including other stock solutions, to make a working solution. For example, to study respiration by isolated mitochondria we need to suspend them in a complex

A dilution is a solution made by adding more solvent to a more concentrated solution ( (known as stock). These solutions are then diluted to the required strength as and when required for the individual patient.
