Though he took to heal the pain, pure aspirin, if taken much can hurt you in the stomach. Why?
Materials Required
Experience
The experiment was performed in the presence of an adult
The explanation
The blue potion became green cabbage with baking and pink
with lemon juice, if the contents of both vessels was mixed,
Bubbles formed and the liquid became blue.
Cabbage blue pigments have been released into the water. Change
color when in the presence of products which react with them.
These changes vary if the color pigments react with an acid,
as lemon juice, or what we call base, like baking.
When a base is reacted with an acid in suitable proportions,
are transformed into a product which is acidic or basic, but neutral.
It is said to be neutralized.
So that cabbage juice resumes its normal color when mixed
in the same glass with lemon and baking.
Application
The acidity control is important in many
industries. Medications each have their acidity.
For example, aspirin is acidic, which means that in the
tablets are mixed with a commodity to avoid
stomachache. Preserved food cans
should not be attacked by food acids
they contain. The taste of the butter depends
its acidity.
The bath products and beauty are not
all the same acidity. You can check their reading
tag: sometimes indicated acidity, writing “pH”
(Measurement of acidity) followed by a number. A
acid product when its pH is less than 7; basic
when greater than 7 and neutral when equals 7.]
