pH of two compounds in water
« on: November 25, 2009, 08:22:06 PM »
calculate the pH of the solution prepared by adding .10mol each of hydroxylamine and hydrochloric acid in 500ml of water.

I was trying to set this up and my understanding is that these two compounds are in water and are "reacting" together to form hydroxylamine hydrochloric acid. with that said the OH in the product would be the determining factor for pH. so would I use the Ka of hydrochloric acid to find OH and then find pH

I just need to understand how the compounds relate to each other in an equation

Both compounds react to form salt. Since hydroxylamine is a wek base this sult undergoes hydrolysis. You need Ka or Kb of hydroxylamine for pH calculation.
