Answer:
Phosphoric acid
Explanation:
Phosphoric acid is an oxyacid, which is formed when hydrogen combines with the polyatomic ion phosphate. The polyatomic ion for phosphate is . To combine this with hydrogen, we "criss-cross" the charges of phosphate (which has a charge of -3) and hydrogen (which has a charge of +1) to get
, the same as
.
To answer this question, we essentially reverse these steps. First, we would recognize that this is a hydrogen atom bonded with phosphate. Because phosphate is a polyatomic ion, we know that this is an oxyacid. Because it involves phosphate, we call it phosphoric acid.
I hope this helps!
Answer:
True
Explanation:
Ethers react with HI to form the corresponding alcohols and alkyl iodides.
Similarly, ethyl ether react with excess of HI to form ethanol and ethyl iodide. But in the excess of HI as mentioned in the question, ethanol too undergoes reaction with HI to form ethyl iodide.
<u>Hence, ethyl iodide is the only product when ethyl ether reacts with excess of HI for several hours.</u>
