Making The Solution

1. Definition of Molarity

Molarity states that the number of mole of dissolved substance in one liter solvent

2. Equation of Molarity

V1 . M1 = V2 . M2

In which :

V1 = Volume of first solution

M1 = Molarity of first solution

V2 =Volume of second solution

M2 = Molarity of second solution

3. Making solution activity

To make 100 ml HNO3 3M from slab of HNO3 (15,4 M).

Known : M1 = 15,4

V2 = 100 ml

M3 = 3

Ask : V1 = ………..?

Solution: V1M1 = V2M2

V1 x 15,4 = 100x 3

V1 = 300/15,4

V1 = 19,43 ml

Making Solvent Main Blue Metilen

Work Procedure

ADD 1.48 gr blue metilen into 100 ml of alcohol 98%

 still the need to be diluted more in the way degan add 9 parts water pipe for each one the parent solution

Dilution alcohol

Alcohol 40 %

Work Procedure

pour alcohol on the glass measuring at 40% and add water until the number reaches 100 ml

4. Some Examples Of Making Solution

• To make solution of Sulfat Acid ( H2SO4 1 M )

• To make solution of Hydrokside Natrium ( NaOH 1 N )

• To make solution of Sulfat Cooper ( H2SO4 ) 0,1 M

• To make solution of Kaliumdikromat ( K2Cr2O7 0,1 N )

• To make solution of Amilum 1%
