How does sugar affect the surface tension of water using scientific methods ?

Chemistry
1 answer:
pentagon [3]3 years ago
6 0
"The surface tension in water is due to the hydrogen bonds in it. When the sugar is added to it, the dissolution process occurs which leads to the breaking of the hydrogen bonds in the water by the hydration energy generated by the interaction of sugar and water. Therefore, sugar reduces the surface tension in water. " (yahooanswers)

Calculate the pH of the cathode compartment solution if the cell emf at 298 K is measured to be 0.660 V when (Zn^2+)=0.22 M and(
yaroslaw [1]

Answer:

pH = 2.059

Explanation:

At the Cathode:

The reduction reaction is:

2H^+ + 2e^- \to H_2   \ \ \ \mathbf{E^0_{red}= 0.00 \ V}

At the anode:

At oxidation reaction is:

Zn \to Zn^{2+} +2e^-   \ \ \ \mathbf{E^0_{ox} = 0.76 \ V}

The overall equation for the reaction is:

\mathbf{Zn + 2H^+ \to Zn^{2+} + H_2}

The overall cell potential is:

\mathbf{E^0_{cell}= E^0_{ox} + E^0_{red}}

\mathbf{E^0_{cell}= 0.76 \ V +0.00 \ V}

\mathbf{E^0_{cell}= 0.76\ V}

Using the formula for the Nernst equation:

E = E^0 - ( \dfrac{0.0591}{n})log (Q)\\

where;

E = 0.66

(Zn^2+)=0.22 M

Then

0.66 =0.76- ( \dfrac{0.0591}{2})log \bigg ( \dfrac{[Zn^{2+} ] PH_2}{[H^+]^2} \bigg )

0.66 =0.76- 0.02955 * log \bigg ( \dfrac{0.22*0.87}{[H^+]^2} \bigg )

3.4 = log ( 0.1914) - 2 log [H⁺]

3.4 = -0.7180 - 2 log [H⁺]

3.4 + 0.7180 = - 2 log  [H⁺]

4.118  = - 2  log  [H⁺]

pH = log [H⁺] = 4.118/2

pH = 2.059
