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:
0.04 mol
Explanation:
Given data:
Mass of barium = 5.96 g
Moles of barium = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of barium = 5.96 g/ 137.33 g/mol
Number of moles = 0.04 mol
Thus the number of moles of barium in 5.96 g are 0.04 moles. The chemist weight out the 0.04 moles .
