Question

20. Which of the following is correct according to
equivalent concept?
(1) W1/W2=E1/E2
(2) NV(ml) =W/E x1000
(3) E=W/NV(L)
(4) All of these​

Answer 1

Answer:4) all of these

Explanation:

N = W/E ×1000/Vml

Answer 2

Answer:

4. All of these​

Explanation:

• (1) W1 / W2 =  E1 /E2
• (2) NV (ml) =W / E x 1000
• (3) E = W / NV(L)
• All the three are correct according to equivalent concept.
• Equivalents theory elemental mass equivalent. The equivalent is the amount of 1.008 parts by mass of hydrogen, 8 parts by mass of oxygen, and 35.5 parts by mass of chlorine that react or displace from a compound.
• It is not always possible to calculate the equivalent weights of chemical entities using this traditional notion. This is the case because humans are unable to imagine chemical processes involving the three named substances hydrogen, oxygen, and chlorine. By employing this concept of comparable weight, we are often restricted to determining the equivalent weights of elements and a select few compounds.
