What is the equivalent mass of Na?
Instead, these chemists had settled on a list of what were universally called “equivalents” (H = 1, O = 8, C = 6, S = 16, Cl = 35.5, Na = 23, Ca = 20, and so on).
What is the equivalent weight of H _{ 3 }* P * O _{ 4 in the following equation H 3 PO 4 +2naoh Na 2 HPO 4 +2h 2 O?
Hence equivalent weight of ${H_3}P{O_4}$ $ = $ Molar mass of ${H_3}P{O_4}$$/$ n factor $ = \dfrac{{98}}{2} = 49$ gram per equivalent.
What will be the equivalent weight of h3po4 in the reaction Ca OH 2 h3po4 cahpo4 2h2o?
Equivalent weight of H3PO4 is 49.
What is the equivalent mass of Na 2 CO 3?
106 g/mole
Answer: 53 g/eq The salt Na2CO3 ionizes to produce 2Na+ and CO3-2. So the charge on both ions is 2. Therefore, the molar mass of Na2CO3 is 106 g/mole.
What is N factor in equivalent weight?
n factor is atomic weight or molecular weight by equivalent weight. n factor for acids is its basicity, ie, number of replaceable hydrogen ion per molecule. For exampleg HCl has n factor 1 n H2SO4 has 2 H3PO3 has n factor 2 because when H3PO3 dissociates to form H+ and HPO3^-2.
What is the equivalent mass of H 3 PO 4?
The equivalent mass of phosphoric acid (H3PO4) is 49 .
How do you find the equivalent mass of H 3 PO 4?
The molecular weight of phosphoric acid is; (3+31+16*4)gram/mol = 98 gram/mol. Now Equivalent Weight = 98/3 gram/equivalent = 32.67 gram/equivalents.
How do you find the equivalent mass of H3PO4?
What is the equivalent mass of Na2HPO4 for this reaction?
Here, for example, one mole of Na2HPO4 (acting as acid) can dissociate to give one mole H+ ions, therefore n-factor is 1. And equivalent mass of Na2HPO4 for this particular reaction is nothing but the mol. wt. it
What is the equivalent weight of H3PO4?

What is the equivalent weight of the solution?
An equivalent weight of a solution is defined as the molecular weight of the solute divided by the valence of the solute. Equivalent weight is used for predicting the mass of a substance that reacts with one atom of hydrogen in an acid-base analysis like in titration. The given reaction is: Ca (OH) 2 + H 3 PO 4 → CaHPO 4 + 2H 2 O
How do you calculate equivalent mass of a salt?
As such it is defined and can be calculated as follows: the equivalent mass of a salt is defined as the mass of the salt formed when one equivalent of an acid is completely neutralized by one equivalent of a base. \\ce {HCl + NaOH -> NaCl + H2O}.
