- From the glass measure pour water into the bottle

. For the formation of the acidic appearance, the chemicals mentioned in the different composition methods must be added in the exact proportions

6- All chemicals must be taken from bottles or jars with plastic spoons designated for that purpose.

After making sure that no chemical substance should be added to the acid, except that this acid or chemical has completely dissolved in the water.

This acid is used with a liter of distilled water

With a time of 3-5 minutes, depending on the composition of the acid.

This composition is used in the development of sensitive films and paper.

How to install this acid:

... The first solution is placed in containers containing distilled water less than a liter, and shaken well until it dissolves, then the second substance is placed with stirring, and the third and fourth.
