What Is The pH Scale | Acids, Bases & Alkalis | Chemistry | FuseSchool

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 something is acid or alkali. Litmus is red in acids, and blue in alkalis. It comes as red litmus paper and blue litmus paper.

Red litmus paper changes colour from red to blue under alkaline conditions, but no change under acidic conditions. Blue litmus paper changes colour from blue to red under acidic conditions, but no change under alkaline conditions.

The pH scale and universal indicator can give more information by telling us how acidic or alkaline something is.

Universal indicator can show many different colour changes and so can be used to test the pH value of the solution.

The pH scale runs from 0 to 14, with 0 being extremely acidic, 7 being neutral and 14 being extremely alkaline.

I think I learned more here than in a normal lesson in school. Maybe because there weren't 25 other children making noise and there wasn't the other teacher walking around looking across your shoulder at your work and making you extremely nervous. But I still learnt more. Thank you for making this.

Im doing online lessons and i don’t understand anything the teacher show us

[realrandiee]

Who's doing this for online classes?

[nizerpabellon]

I love watchin' some random chemistry videos; but it really hits different when you have to watch it because of online learning.

Thanks, you just helped someone trying to find out what pH scale was :)

[saudalthani]

pH scale was shown online class by the teacher . So it was easy to understand it

That’s it. I’m failing science. I give up, imma go to sleep, do my test, fail, parents evening is soon but I honestly don’t care I’m 3 years in & im still clueless I don’t know anything & my teacher is such a bad teacher ffs, when my gcse science comes ik imma fail & I give up tryna tell myself I can do this I CANT DO

Think about it if YouTube just banned learning stuff on it we wouldn’t have to do as much work

[sajatelb]

I know right I took the exam already nervous about the results

[AirbusA-yxsz]

I’m doing this in self isolation because my teacher told me to

[mirandamanga]

This should video should be renamed into “pH Indicators” instead.
