Wow! Thank you :)
WHAT AN AMAZING SUMMARY
Thank you! Hope it was helpful :)
SOOO underrated! thanks so much for this!
Happy to help!
What about hydroxide you mentioned that you would be going over them in the introduction?
At 1:18 he said the red litmus paper test can also be used to test for hydroxide ions
So for white precipate formations is it only for aluminium, calcium and zinc
i love you
how about ammonia ions
Ammonia isn't ionic - it is a molecular substance (made up of NH3 molecules) - there are no ammonia ions. We can test for ammonia molecules however using damp, red litmus paper. Hope that helps :)
