Solutions
1. Percent solution (w/v) · One percent solution of a substance contains one gram of the substance in 100ml of the solvent. · If v/v is given, it means 1 ml in 100ml of solvent. · %( w/v): The weight in grams of a solute per 100ml of solution. · %( w/v): The weight in grams of a solute per 100ml of solution. 2. Molar solution (M) · One molar solution of a substance contains one mole or one-gram molecular weight of the substance in one liter of solution. · E.g.1 M NaOH in one solution . · Likewise, one milli molar solution of a substance contains one-milligram molecular weight of the substance in one liter of solution. · E.g.1mm NaOH contains 40mg NaOH in one liter of solution. 3. Normal solution (N) · One normal solution of a substance contains one equivalent or one gram equivalent weight of the substance in one liter of solution (i.e., molecular weight divided by the hydrogen equivalent of the substance). · E.g. 1N H2SO4 contains 49g H2SO4 in one liter solution |
