  • What am i forgetting!?!?
  • Ohhh!!! I just remembered, we have a chemistry test today!!!
  • What is it on!?!?
  • Don't you know it's cations?!?
  • What is that??? Can you teach me???
  • Yea sure!!!
  • Oh ok.So how exactly do they react with diffrent substances
  • So basically, cations are positively charged ions, they react differently with different substances
  • Ok so, Ammonium after reacting with NaOH forms ammonia, on warming, turns litmus paper from red to blue. Also ammonium doesn't react with NH4OH
  • What else??
  • Also, Ferris, which is Iron, when mixed with NaOH makes a red-brown precipitate, it is insoluble in excess. And when it is mixed with NH4OH it also creates a Red-brown Precipitate, it is insoluble in excess
