What is the ph of a solution with [h3o+]= (8.70x10^-5). enter your answer in scientific notation and with three significant figures.

Hey there!:

We know that :

pH = - log [ H₃O⁺ ]

pH = - log [ 8.70 x 10⁻⁵ ]

pH = 4.06

Therefore pH is 4.06

I hope this will help !

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
