First we will be solving pH for before equivalence

Equivalence point is a point where all acid is neutralized by base.

The pKb of ethylamine is 3.19. Calculate the pH of the base solution after the chemist has added 10.2mL of the HIO3 solution to it. 

Calculate the pH before equivalence?
At equivalence?
After equivalence?

Its a lot to digest but stay with me here]]> 2022-11-26 05:47:01 UTC https://padlet.com/jecheverry51/n85ynj7ewnv6yrow/wish/2398413145 jecheverry51 https://padlet.com/jecheverry51/n85ynj7ewnv6yrow/wish/2398413146 Relax and breathe maybe even do a little dance before starting. Let us begin shall we. Read the entire problem and write down the information it contains.]]> 2022-11-26 05:47:01 UTC https://padlet.com/jecheverry51/n85ynj7ewnv6yrow/wish/2398413146 jecheverry51 https://padlet.com/jecheverry51/n85ynj7ewnv6yrow/wish/2398413147 No please don't get so discouraged after seeing it. Like Luis Fonsi and Farruko once said "Vamos a darle despacito"

Same here]]> 2022-11-29 23:15:09 UTC https://padlet.com/jecheverry51/n85ynj7ewnv6yrow/wish/2402692348 jecheverry51 https://padlet.com/jecheverry51/n85ynj7ewnv6yrow/wish/2407357057 So basically the problem is asking for the pH at the equivalence point.
After equivalence and before equivalence?
Perfect we know what its asking three different questions relating to the pH of the solution.
