Answer 1

Respuesta:

Bueno, pues es la explicación y procedimiento de un experimento sencillo.

Se lo pasare en ingles para que solo lo copie y ya.

The experiment of invisible dye with lemon.

Materials:

-A lemon.

-A lighter.

-A few toothpicks.

-A sheet of paper.

Procedure:

First we squeeze a lemon.

We grab some chopsticks and soak them in lemon juice.

Then we write what we want on a piece of paper.

And we’ll heat it with the lighter, at a moderate distance so the paper doesn’t burn.

Everything we had written now can be seen.

How is it done properly?

It is a simple experiment, therefore, to perform it is easy.

A recommendation would be not to bring the paper too close to the lighter, the paper could burn, and with it our message.

How is it possible that lemon creates invisible ink?

Lemon liquid is a weak acid that when applied to paper weakens it (because it has cellulose). In this way, by giving heat to a flame, the citric acid part of the lemon juice oxidizes leaving a brown substance, which is carbon.

Hey, espero haberle ayudado. Que tenga un buen día.
