A standard solution can be prepared by weighing method in the following way. (a) The mass of solute needed is calculated and weighed. (b) The solute is dissolved in some distilled water in a beaker. (c) The solution is transferred into a volumetric flask.
Why do we prepare standard solutions?
In analytical chemistry, a standard solution is a solution containing a precisely known concentration of an element or a substance. ... Standard solutions are used to determine the concentrations of other substances, such as solutions in titration.
How do you prepare a solution for a titration?
Add approximately 50 ml of water (remember, not tap water) and three drops of methyl red indicator. Fill a 25 ml buret with the 0.1 N sodium hydroxide solution and record the initial volume. Titrate the hydrochloric acid to the point at which a lemon yellow color appears and stays constant. Record the final volume.
