What is the equivalent weight of H3PO2?
(D) 49.5. Hint: As we know that in a chemical reaction the equivalence of a substance is explained as the amount of which combines with 1 mole of the hydrogen atoms or replaces the same number of hydrogen atoms in the reaction. Thus equivalent weight in grams is the weight of 1 grams.
Does H3PO2 disproportionate?
The disproportionation reaction is 3H3PO2 → PH3 + 2H3PO3. Now the conversion of H3PO2 to PH3 involves the addition of 4 electrons.
What will be the equivalent weight of h3po4 in the following reaction?
Equivalent weight of H3PO4 is 49.
What is equivalent weight of PH3?
we know, atomic weight of phosphorus = 31 g. so, equivalent weight of phosphorus in PH3 = 31/3 = 10.33g.
What is the equivalent weight of cl2 when disproportionate into nacl and naclo3?
Therefore, the answer is – option (a) – The equivalent weight of chlorine molecule in the given reaction is 42.6. Additional Information: We use hot and concentrated sodium hydroxide for this reaction.
What is the molecular weight of h3po4?
97.994 g/mol
Phosphoric acid/Molar mass
What is the n-factor when H3PO2 is converted to PH3?
Now, find the n-factor (total change in oxidation number per molecule) and then equivalent mass = molar mass/n-factor. So, when H3PO2 changes into PH3, oxidation state of phosphorous changes from +1 to -3 so as n-factor is 4.
What is the equivalent weight of H3PO2 when it is disproportionate?
The equivalent weight of H3PO2 when it disproportionate into PH 3 and H 3 PO 3 is? The disproportionation reaction is 3H 3 PO 2 → PH 3 + 2H 3 PO 3. Now the conversion of H 3 PO 2 to PH 3 involves the addition of 4 electrons. =4/3. =3M/4. Was this answer helpful?
How do you calculate the mass of a disproportionation reaction?
Build a foundation in nutrition science with this course from the Stanford Center for Health Education. For disproportionation reactions, use a trick to find equivalent mass; E = E1 + E2; where E1 and E2 are equivalent masses of oxidation and reduction half reactions of same element.
What is the equivalent mass of phosphorous in grams?
It is clear that phosphorous is losing and gaining 3 equivalents. Hence, its n-factor is 3. Therefore, equivalent mass of phosphorous is its molar mass / 3, which is 10.32 grams. 8 clever moves when you have $1,000 in the bank.
