Does sugar when dissolved form ions

Chemistry

Answer:

Dissolving sugar is a physical change. It is not a chemical change. So, ions will not be formed.

Explanation:

Sugar will readily dissolve in water but doesn't form cations and anions in solution. That is, there are no charge carriers formed. Substances that only partially ionize into ions when dissolved in water are called weak electrolytes.

I hope it help:)

For a beryllium-gold voltaic cell containing Be2+(aq) and Au3+(aq) solutions, do the following. (a) Identify the cathode. (Inclu
OLEGan [10]

Answer:  Gold act as cathode.

Explanation:

Standard potential for an electrochemical cell is given by:

E^0{cell} = standard electrode potential =E^0{cathode}-E^0{anode}

The E^0 values have to be reduction potentials.  

Reduction potentials for given elements

E^o_{Be^{2+}/Be}=-1.97V

E^o_{Au^{3+}/Au}=+1.40V

The element Be with negative reduction potential will lose electrons undergo oxidation and thus act as anode.The element Au with positive reduction potential will gain electrons undergo reduction and thus acts as cathode.

Cathode : 2Au^{3+}+6e^-\rightarrow 2Au

Anode : 3Be\rightarrow 3Be^{2+}+6e^-

3Be+2Au^{3+}(aq)\rightarrow 2Au+3Be^{2+}(aq)

Thus gold act as cathode.

A solution of pH 5 is diluted 100 times. Find the pH of the resulting solution.
liq [111]
First, we calculate of the concentration of the H+ ions in the solution from the pH given. Then, calculate the new concentration after dilution. Calculation are as follows:

pH = -log[H+]
5 = -log[H+]
[H+] = 1 x 10^-5 M

M1V1 = M2V2
<span>1 x 10^-5 M (V1) = M2(100V1)
</span>M2 = 1 x 10^-7

pH =  -log[<span>1 x 10^-7</span>]
pH = 7
