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?
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

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.
You gay for that bro let him teach me
well spotted 👊🏼
