I would say D. Because if you displace too much water it would would either go to fast or not move at all... that's just my thought

H2PO4-(aq) ⇆ H+(aq) + HPO42-( which ion plays the role of hydrogen ion donor and which one plays the hydrogen ion acceptor in BP
alexgriva [62]

Answer:

<u>H2PO4- is a proton donor and HPO42_ is a proton acceptor</u>

Explanation:

Step 1: What are hydrogen ion donor and acceptor

in the following reaction we see that:

⇒ H2PO4- is more likely to give a H+ ion to form HPO42-.  

⇒HPO42- is more likely to take a H+ ion, to form H2PO4-

The reaction of an acid in water solvent is described as a dissociation :

HA ⇔ H+ + A-

⇒where HA is a proton acid

So, H2PO4- = HA   and  HPO42- = A-

Acids are proton donors. So, <u>H2PO4- is a proton donor and HPO42_ is a proton acceptor</u>

What was the weight percent of water in the hydrate before heating?
DedPeter [7]
Data:

weight of water before heating = 0.349

weight of hydrate before heateing = 2.107

Formula:

Weight percent of water = [ (weight of water) / (weight of the hydrate) ] * 100

Solution:

Weight percent of water = [ 0.349 / 2.107] * 100 ≈ 16.6 %

Answer: 16.6%
