procedure:-1) Take one glass and added hydrochloric acid.
                     2) Copper cubes is placed in the flame of blow                                  lamp for heating.

                     4) solder metal is kept on the area to be soldered.                       It is heated using red hot copper cube. solder                              metal. It solidifies to make perfect soldered joint
Observation:-1)Why flux is used for soldering.
                         2) Why acid is used to make flux

Conclusion:-1)a metal whose melting point is below the                                    melting point of a job is used to join the job.
                       2) Soldering is used to solder job for less                                        thickness
