Answer is: false, concentration of hydroxide ions is greater in lye than in household bleach.
1) pH = 12.6.
pH + pOH = 14.
pOH = 14 - 12.6.
pOH = 1.4.
pOH = -log[OH⁻] ⇒ [OH⁻] = 10∧(-pOH).
[OH⁻] = 10∧(-1.4) = 0.039 M; concentration of hydroxide ions.
2) pH = 13.
pOH = 14 - 13.
pOH = 1.
[OH⁻] = 10⁻¹ M = 0.1 M.
0.1 M > 0.039 M.
Answer:
Household bleach has more hydroxide ions than lye.
Explanation:
The pH of the solution id the negative logarithm of hydrogen ion concentration in an aqueous solution.
[tex]pH=-\log[H^+][/tex]
The pH of the household bleach = 12.6
[tex]12.6=-\log[H^+][/tex]
[tex][H^+]=2.511\times 10^{-13} M[/tex]
The pH of the lye= 13
[tex]13=-\log[H^+][/tex]
[tex][H^+]= 10^{-13} M[/tex]
Since , house hold bleach has the lower pH than lye which means that it will have higher concentration of hydroxide ions.
