i'm actually not even a GCSE student but your videos are just so well explained and helpful that I watch them very single day to help me understand my lessons better. Its been so hard to find good videos but ever since I found your videos I've been so much better in class n have been understanding my lessons much better. According to my curriculum ( Cambridge ) I still do have more content on each topic but just cus of the way you explain things so simply I just can't leave you even though I can't fully depend on these videos for my lessons. Thankyou so much I really love your videos and I wud reccoment them to anyone any day 💕

[@ronaldmcdonald8303]

From what I gather, acids are good at destroying hair, metals and some other organic materials, but don't work well of greases and fats, Alkaline don't damage metals but are brilliant at removing scum and fatty substances. Their chemical opposites, one takes an electron and one gives one. Hydrogen peroxide is simply water with an added oxygen atom! I've tried all sorts to unblock my drains, but nothing seems to work, should I get a bottle of pure H2O2?

i have a question.IDo base only produce salt and water? If so how come calcium carbonate is a base as like calcium carbonate will produce carbondioxide as well right?

[@omar1737]

i dunno. maybe because nutrilzation could carbonate and carbonoxide by compounding and mixing salt. Your Welcome

Nope, not just salt and water. Gases are produced too, tho I cant say for all reactions

[@jesswhitford2495]

Hi, I've just had a question on this, in the video there is an example of an acid + base, I think that you mean acid + metal carbonate, which does equal salt+carbon dioxide+water
