Choose the correct statement. The cathode is the electrode where the oxidation takes place. Both oxidation and reduction may tak
gregori [183]

Answer:

The cathode is the electrode where the reduction takes place.

Explanation:

Cell has three components:

an electrolyte and two electrodes which is a cathode and an anode.

Electrolyte is usually solution of the water or other solvents in which the ions are dissolved.

<u>In electrolytic cell:</u>

Negatively charged electrode is the cathode where the process of reduction takes place.

Positively charged electrode is the anode where the process of oxidation takes place.

<u>In galvanic cell:</u>

Positively charged electrode is the cathode where the process of reduction takes place.

Negatively charged electrode is the anode where the process of oxidation takes place.

<u>So, the correct answer is - The cathode is the electrode where the reduction takes place.</u>

What is the percent composition of phosphoric acid H3PO4
Agata [3.3K]
Hey there!:

Molar mass H3PO4 = <span>97.9952 g/mol

Atomic Masses :

H = </span><span>1.00794 a.m.u

</span>P = <span>30.973762 a.m.u

</span>O =  15.9994 a.m.u<span>

H % =  [ ( 1.00794 * 3 ) / </span> 97.9952  ]  * 100

H% = <span>3.0857 %

P % = [ ( </span>30.973762 * 1 ) / 97.9952 ] * 100

P% = <span>31.6074 %

O % = [ ( </span>15.9994 * 4 ) / 97.9952 ] * 100

O% = <span>65.3069 %
