A solution with a pH value which is less than 7 is acidic. The acids which react with metals usually have quite a low pH, of either 3 or less. Some metals react with acids and when they do the ...

The spectacular reaction of alkali metals with water was poorly understood — despite being a staple of chemistry classes. It’s the classic piece of chemical tomfoolery: take a lump of sodium or ...

Here you get the CBSE Class 10 Science chapter 1- Chemical Reactions and Equations: NCERT Exemplar Solution (Part-II). This part of the chapter includes solutions for Question No. 22 to 44 from the ...

Chemists have discovered the key reaction that takes place in sodium-air batteries that could pave the way for development of the so-called holy grail of electrochemical energy storage. Chemists at ...

CBSE Class 12 Important Chemical Reactions: The CBSE Class 12 Chemistry exam for 2026 is scheduled for February-March. The exam will cover physical, inorganic, and organic chemistry, so it’s important ...

Lights, camera, kaboom! With snapshots from a high-speed camera, chemists can finally explain why sodium and other alkali metals blow up in water. “What we found out is that there’s a crucial piece of ...

Fuel cells that react liquid sodium metal with air could be the power source required to give electric airplanes much longer ranges, a new paper has proposed. The idea has yet to leave the laboratory ...
