hope this helps!
First calculate the electric charge used to deposit 1.0 g Pt
C = (1.0 g Pt) (1 mol Pt / 195.1 g Pt) ( 2 mol e / 1 mol Pt)
( 96485 C / 1 mol e)
C = 989.08 C
C = It
Where I is the current
T is the time
T = C / i
T = 989.08 C / 0.15 A
T = 6593.88 s
T = 1.83 hrs
Answer:
Reactants
Explanation:
They become known as reactants
Answer:
The answer to your question is pH = 5
Explanation:
Data
[H⁺] = 1 x 10⁻⁵
pH = ?
pH is a measure of the hydrogen concentration. It measures the acidity or alkalinity. The range of pH goes from 0 to 14. The pH for an acid is from 0 to 6.9, for a neutral solution is 7.0 and for an alkali is from 7.1 to 14.
Formula
pH = -log [H⁺]
-Substitution
pH = -log [1 x 10⁻⁵]
-Simplification
pH = - (-5)
-Result
pH = 5
