Hydrolysis of Salts
Determine the pH of salt solutions using acid--base indicators. Certain cations or anions in salts react with water to produce H+ or OH-- ions, respectively.

well I couldn't understand this process from the book but by watching your video I gained some useful knowledge.
No one shows us these things. Thank you so much
Awesome demonstration,loved it
We don't have these kind of teachers 😓

This helped me get past the concept of donating and accepting H+ ions to determine if the solution will be basic or acidic. I kept missing simple questions on my homework of this type. So the conj. acid/base of a strong electrolyte will not react because it most likely will be weak but the conj. acid/base of a weak electrolyte WILL indeed react and produce either H3O+ or OH- ions in solution which either raises or lowers the pH. Let me know if I am mistaken, thanks so much FlinnScientific!
do u know laboratory preparation of inositol from rice bran??
I was really curious about how , acids or bases can be taken from salt. And this video helped me understand the process. Well I didn't understand the whole thing ,but a part of it is clear to me.
in which liquid you mixed the salts
Where do you get your salts
It's beautiful !!!
Question: I ph my tap water to water my plants. My tap water comes in at 8.0. I had a general hydroponics to ph down. If the water sits for a few days the ph will go back to ph of 8.0. No nutrients have been added to water just simply ph down….why does it go back up is the acid leaving the water?
Thank you so much for this video.....

I"M HERE BECAUSE OF MY CHEMISTRY LAB REPORT
I just don't understand why all solid salts look all the same!!
Why did the indicators change color? Aren't salts neutral? I mean, except potassium carbonate and the hydrogenphosphates?

Indicators chaneged colors because of pH change. Salts are neutral, but salt solutions can be acidic or alkaline because when the reaction between a strong acid and a weak base (or weak acid and a strong base) stops, the salt solution has still some acid or base left in it (more H+ ions or more OH- ions).
Nice?
