Answer:
+5
Explanation:
The oxidation number of phosphorus can be obtained as follows:
H4P2O7 = 0
4(+1) + 2P + 7(—2) = 0
4 + 2P —14 = 0
Collect like terms
2P = 14 — 4
2P = 10
Divide both side by 2
P = 10/2
P = +5
The oxidation number of phosphorus is +5
Answer:
d) BaF2
Explanation:
The compound which is more soluble in an acidic solution than in a neutral solution is shown below:-
First we will compare acidic with Neutral
So,
Now, when we add H+ ions, so it will be
Then it will reduces F-, as BaF2 begin to form more aqueous ions, so, it will rises the solubility
