Learn the basics about the pH scale, universal indicator and litmus paper. Indicators tells if something is acidic, alkaline or neutral. Indicators are substances that show different colours when they are in acidic or alkaline conditions. Litmus paper is a simple indicator that tells us whether so
The pH value calculation for weak acids (and bases) is explained. This is more demanding than with strong acids and bases. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.

Bisphenol A - or BPA for short - is one of the more contentious chemicals on the block at the moment. Companies making BPA, and the products that contain it, claim that the substance is safe if used sensibly. But others aren't so sure. But before getting into the risks and benefits, it makes sens
Using methyl orange as an example, the function of acid-base indicators is briefly explained. At the end, the different colours are discussed. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done by the alugha AI.
A power is also known as an index number, or indices for plural. They tell us how often a number or letter has been multiplied by itself. In this video we are going to look at index notation, so that we are ready to cover the laws of indices in future videos. Our teachers and animators come toget
There are many reasons to keep quiet. Sometimes it’s better to listen, or maybe you don’t want to draw attention to yourself. Your reasons can have a negative or positive impact. But what happens when you’re quiet for so long that you get used to it? These are the reasons why you are so used to bein
