Question

Need help asap please!
1. Chemists define the acidity or alkalinity of a substance according to the formula pH = –log[H+] where [H+] is the hydrogen ion concentration, measured in moles per liter. Solutions with a pH value of less than 7 are acidic; solutions with a pH value of greater than 7 are basic; solutions with a pH of 7 (such as pure water) are neutral.
a) Suppose that you test apple juice and find that the hydrogen ion concentration is [H+] = 0.0008. Find the pH value and determine whether the juice is basic or acidic.
b) You test some ammonia and determine the hydrogen ion con

Answer 1

@roz_mar23 @shifuyanli can one of you guys help?

Your second question got cut off @_ashleeey

Answer 6

-log[H+]*
Anyway... so, you need to replace the [H+] in the formula with 0.0008, and log that:\[pH=-\log0.008\]

Answer 7

0.0008 omg my keyboard hates me.

Answer 8

heres 2, b) You test some ammonia and determine the hydrogen ion concentration to be [H+]= 1.7 × 10–8. Find the pH value and determine whether the ammonia is basic or acidic.

Answer 9

Please type new questions in a new post. :)

Answer 10

But you go through the same process in that question too. Just replace the [H+] in the formula with the equation you're given.

Answer 11

Don't for- oh you closed the question.
Medal to you, though! :p
