Which mixture is salt solution​
VARVARA [1.3K]

Answer:

Below

Explanation:

Salt solution, aka saline solution, is a homogeneous mixture. This means that the mixtures composition is completely uniform throughout. If you were to look at a saline solution, it would just look like plain water because the salt is dissolved (it looks the exact same in the entire mixture).

      Something like bean soup would be an example of a heterogeneous mixture. You can see all the beans and vegetables as components of one mixture.

Hope this helps! Best of luck <3

Purification of chromium can be achieved by electrorefining chromium from an impure chromium anode onto a pure chromium cathode
mylen [45]

Answer:

696 h

Explanation:

Let's consider the reduction of Cr³⁺.

Cr³⁺(aq) + 3e⁻ → Cr(s)

We can establish the following relations.

  • The molar mass of Cr is 52.0 g/mol.
  • 1 mol of Cr is deposited when 3 moles of e⁻ circulate.
  • 1 mole of e⁻ has a charge of 96468 c (Faraday's constant).
  • 1 A = 1 c/s
  • 1 h = 3600 s

<em>How many hours will it take to plate 13.5 kg of chromium onto the cathode if the current passed through the cell is held constant at 30.0 A?</em>

13.5 \times 10^{3} gCr.\frac{1molCr}{52.0gCr} .\frac{3mol/e^{-} }{1molCr} .\frac{96468c}{1mol/e^{-}} .\frac{1s}{30.0c} .\frac{1h}{3600s} =696 h
