You cannot know how much your videos help us! Man you are a legend ❤️❤️❤️

[@Cognitoedu]

Happy to hear that! 🙌

I just test for gases by inhaling, it's a fun kind of Russian roulette in class.

Anyone been sent here by a teacher in lockdown

[@geezer1024]

small error I think: 2:53 in the equation for co2 and ca(OH)2 you say that Ca(OH)2 is a gas in the state symbol when I think it is aqueous.

Thank you for this video but I just have a question when talking about the litmus paper turning red because chlorine dissolves in the water on the blue litmus paper you said that hydrogen chloride is made but isn't a reaction between chlorine and H20, hypochlorous acid?

[@jungoonosebiter]

Nono you see when you damp a litmus paper there's water means there's H2O so when it reacts with chlorine you get HCI, hydrochloric acid (the blue litmus paper turns red becuz its acidic) but then it will become HOCI (hypochlorous acid) because chlorine bleaches so litmus paper becomes from red to white

@@CauseOfBSOD i appreciate the clarification bro

[@AliKayani-ng6qt]

​@CauseOfBSOD I thought u were serious lol

[@whyyoulooking4944]

And why the litmus paper in chlorine test turned white or colourless and what is meant by bleached?

[@teenagegirl43]

Bleached means it turns white

[@MuslimEDUOfficial]

instructions unclear:i ended up hallucinating carbon monoxide instead of bubbling CO2 in the beaker of limewater, now my hands are cloudy and white instead
