How to Dilute Solutions

The equation has four components: C1 = Initial concentration of solution V1 = Initial volume of solution C2 = Final concentration of solution V2 = Final volume of solution Put together, the equation translates to: the starting concentration multiplied by the starting volume is equal to the final concentration multiplied by the final volume. Basically, if you have three of the four components of the equation then you can use these within the formula to calculate the unknown component. All you have to do is to rearrange the formula for your needs. Problem text: We have a 5M solution of NaCl. We want 100mls of solution. C1V1 =C2V2 ;5MxV1 = V1 = ( x 100ml)/5M V1 = 50ml/5 V1 = 10ml Add 10ml of 5M NaCl to a container and bring the volume to 100ml with water. #solvent #solution #solute #concentration #StockSolutionDilution
