Answer: 5.48
Explanation:
pH is the negative logarithm of hydrogen ion concentration in a solution.
Mathematically, pH = - log(H+)
where H+ represent the concentration of hydrogen ion
So, to get the pH of the solution with [H +] = 3.25×10-6 M:
Apply, pH = -log(H+)
pH = - log (3.25×10-6 M)
pH = - ( -5.48)
(Note that the minus signs will cancel out each other)
Therefore pH = 5.48
Now we know that the pH of the solution with hydrogen ion concentration of 3.25×10-6 M is 5.48 (i.e slightly acidic)
Thus, we can finally say 5.48 is the pH of the solution within a solution with pH = 4.50
Answer:
This is the answer of your question. ☺☺
Explanation:
Percentage composition of Cu is 71.54.
Percentage Composition of Br is 29.54.
Call what you have to find is x
nHCl/V=12M
nHCl=2.0,25=0,5
->x=0,5.12=6 (600 ml)
Compounds with different boiling points - b.
Only because<span> fractional distillationworks by having a temperature gradient in the column therefore different length hydrocarbons condence at different rays of different temperatures.This works because longer chain hydrocarbons have higher boiling points. </span>
