A simple summary for all

00:03 Hydrogen is the first element in the periodic table.
02:42 The debate started when Mendeleev placed hydrogen at the first position in the periodic table.
07:40 Hydrogen and alkali metals are both good reducing agents.
10:08 Hydrogen and alkali metals react with non-metals to form respective compounds.
15:07 Hydrogen, fluorine, chlorine, bromine, iodine, etc. are two-atomic substances.
17:36 Hydrogen is a key element found in water, acids, and alkalis.
21:59 Potassium reacts with water to form potassium hydroxide and hydrogen gas.
24:16 Sodium reacts with water to form sodium hydroxide and release hydrogen gas
28:21 Reactivity of metals decreases in the activity series
30:29 Hydrogen is released by higher elements in the reactivity series.
34:45 Hydrogen gas can be produced by reacting zinc granules with dilute acid
36:59 Zinc granules are used as a catalyst in the hydrogen reaction.
41:17 Water gas is a combination of carbon monoxide and hydrogen
43:43 Hydrogen can be obtained by passing a mixer through water or caustic potash.
48:21 Chlorine removing hydrogen is a form of oxidation
50:47 Reduction is the process of removing oxygen, adding an electro positive ion, and removing an electronegative ion.

Wish you good luck for your exam guys 👍

[amratameghani]

sir atmospheric pollution pls
best teacher ever sir tarun rupani
always the best

[iitmotivation]

Sir chemical name of water is dihydrogen oxide 😊

[Jaiman_shah]

Best teacher of icse ❤❤
Thank you very much sir for helping us in learning all the chapters very easily and making the concept clear and easy

[harshitkashyap]

Sir, literally I don't know how to thank u tomorrow is my exam and it took me just 1 hour and I am done with full chapter
Thank u soooo much❤ sir

[aradhanakumari]

OIL- oxidation is loss of electrons
RIG- reduction is gain of electrons

Why Henry Cavendish was given credit for discovery and not boyle:





Henry Cavendish is credited with the discovery of hydrogen primarily because of his detailed and accurate study of the gas, which allowed him to identify it as a distinct substance. Although Robert Boyle had produced hydrogen gas in 1671 by reacting metals with acids, he did not recognize it as a separate element. Boyle's observations were more general, and he did not thoroughly investigate the properties of the gas.

In 1766, Cavendish carried out a series of experiments in which he systematically collected and studied the properties of the gas released when metals reacted with acids. He identified it as a distinct "inflammable air" and recognized its unique characteristics, such as its ability to burn and form water when combusted. Cavendish’s work laid the foundation for understanding hydrogen as an element, which is why he is often credited with its discovery, despite Boyle's earlier preparation of it.

Thank you sir for your best explanation🎉

[susheelpandey]

Thx sir for explaining 😊 the consept as well mannered way

[internetqueen]

40:19 Manufacture of hydrogen (Bosch process) if anyone needs it.

[spingamer]

SIR YOUR EXPLANATION IS AWESOME love your teaching and love your enthusiasm keep doing what you do the best being exclusive kudos

[leokage-]

41:48 you are wrong it is endothermic reaction, not exothermic. Heat is absorbed not expelled.

[vidyakakkanavar]

Thank you so much sir seeing the full video I understood what is hydrogen and you teach better than my school tr
Clear explanation aur apni basha mein
Thank you so much sir mere knowledge str🌟☺️☺️

[SAINI_]

❤ congratulation sir for 300 k subscriber🎉🎉🎉🎉❤❤❤❤❤

[adeebimam]

Sir u r literary the best icse helper and very underrated teacher ❤

[ayushiojha]

Sir pls make vedio on study of gas laws in chemistry.

[Kinggaming]

Who is watching 1day before exam 👇attendence lagao 😊😂
