Write a balanced half-reaction for the product that forms at each electrode in the aqueous electrolysis of the following salts:(
likoan [24]

Balanced Half reactions are:

At anode 2Cl^{-}  ==> Cl₂+ 2e^{-} + H₂O ==> ClO^{-}+ 2H^{+} + Cl^{-}

At Cathode:  2H^{+} + 2e^{-} ==> H₂

Since the question states that you are using an aqueous solution of MnCl₂,  so ions will have present are, H₂O, H^{+}, Mn^{2+} and Cl^{-}

Now at Anode reaction will occur as given:

2Cl^{-}  ==> Cl₂+ 2e^{-} + H₂O ==> ClO^{-}+ 2H^{+} + Cl^{-}  (will occur)

At Cathode:

2H^{+} + 2e^{-} ==> H₂ (will occur)

At Cathode:

Mn^{2+} +  2e^{-}==> Mn (This reaction will not occur)

The deposition of solid Mn will not occur because in aqueous solution, H^{+}will be reduced before Mn^{2+} .

The reduction potentials for H^{+} is zero whereas reduction potential for Mn^{2+} is - 1.18V.

The reduction potential of a species is its tendency to gain electrons and get reduced. It is measured in millivolts or volts. Larger positive values of reduction potential are indicative of a greater tendency to get reduced.

An order is given to administer 57 g of lactulose syrup, often used for treating complications of liver disease. The suspension
Angelina_Jolie [31]

Answer : The volume given to the patient should be, 85.5 mL

Explanation :

As we are given that the suspension contains 10g/15mL.

Now we have to determine the volume should be given to the patient.

As, 10 grams of lactulose syrup needed 15 mL volume of solution

So, 57 grams of lactulose syrup needed \frac{57g}{10g}\times 15mL=85.5mL volume of solution

Thus, the volume given to the patient should be, 85.5 mL
