Tittle:

Preparation of Making x mL AgNO3 x M from AgNO3 (s)

Date of Experiment:

26th, February 2014

Objective:

To make solution of x mL AgNO3 x M from AgNO3 (s)

Basic Theory:

Seperti yang ada dibuku dengan tambahan pembuatan beberapa larutan khusus (buffer, standar pH, dsb)

Tools and Materials:

Tools Materials

Spatula (1)

Watch glass (1)

Balance (1)

Funnel (1)

Pipette (1)

Volumetric flask 500mL (1)

Beaker glass 50 mL (1) -> pakai ta???

Wash bottle (1)

AgNO3 (s)

Aquadest

Procedure: -> kalau pakai beaker glass berarti ditambah, gmna???

1. Weighting AgNO3 (s) for xx g in balance by using watch glass

2. Taking AgNO3 (s) into volumetric flask by using funnel

3. Washing the watch glass and funnel by using wash bottle, so there is no solid of AgNO3 that left in both watch glass and funnel.

4. Adding aquadest into volumetric flask until fulfill ¼ of the flask.

5. Shaking the volumetric flask until the solution dissolve

6. Adding aquadest until the limited sign in volumetric flask is reached.

7. Taking the solution that has been made out to the other bottle for solution of AgNO3 x M

Design of Experiment:

Conclusion:

X mL AgNO3 x M can be made by diluting x g AgNO3 in volumetric flask 500mL.
