Hello!

datos: Molarity = 1.0*10^{-4}\:M\:(mol/L)

ps: The ionization constant of the sulfuric acid is strong and completely dissociates in water, so the pH will be:

pH = - log\:[H_3O^+]

pH = - log\:[1*10^{-4}]

pH = 4 - log\:1

pH = 4 - 0

\boxed{\boxed{pH = 4}}\end{array}}\qquad\checkmark

Note:. The pH <7, then we have an acidic solution.

I Hope this helps, greetings ... DexteR!

Answer:

The pH of the sulfuric acid solution is 3.70.

Explanation:

The pH is negative logarithm of hydrogen ion concentration.

pH=-\log[H^+]

Concentration of sulfuric acid = \times 10^{-4} M

H_2SO_4(aq)\rightarrow 2H^+(aq)+SO_{4}^{2-}(aq)

1 mole of sulfuric acid gives 2 moles of hydrogen ions.Then1.0\times 10^{-4} M of sulfuric acid will give .

[H^+]=2\times 1.0\times 10^{-4} M=2.0\times 10^{-4} M

The pH of the solution :

pH=-\log[2.0\times 10^{-4} M]=3.70

g 304 mL of a 0.36 M potassium hydroxide solution is added to 341 mL of a 0.51 M lithium hydroxide solution. Calculate the pOH o
Liono4ka [1.6K]

Answer:

<u><em></em></u>

  • <u><em>pOH = 0.36</em></u>

Explanation:

Both <em>potassium hydroxide</em> and <em>lithium hydroxide </em>solutions are strong bases, so you assume 100% dissociation.

<u>1. Potassium hydroxide solution, KOH</u>

  • Volume, V = 304 mL = 0.304 liter
  • Molarity, M = 0.36 M
  • number of moles, n = M × V = 0.36M × 0.304 liter = 0.10944 mol
  • 1 mole of KOH produces 1 mol of OH⁻ ion, thus the number of moles of OH⁻ is 0.10944

<u>2. LIthium hydroxide, LiOH</u>

  • Volume, V = 341 mL = 0.341 liter
  • Molarity, M = 0.51 M
  • number of moles, n = M × V = 0.341 liter × 0.51 M = 0.17391 mol
  • 1mole of LiOH produces 1 mol of OH⁻ ion, thus the number of moles of OH⁻ is 0.17391

<u />

<u>3. Resulting solution</u>

  • Number of moles of OH⁻ ions = 0.10944 mol + 0.17391 mol = 0.28335 mol

  • Volume of solution = 0.304 liter + 0.341 liter = 0.645 liter

  • Molar concentration = 0.28335 mol / 0.645 liter = 0.4393 M

<u />

<u>4. </u><em><u>pOH</u></em>

      pOH=-\log [OH^-]=-\log (0.439)=0.36   ← answer
