Hydrolysis involves the reaction of water with another compound.Hydrolysis is the process in which the bond breaks due to addition of water whereas in hydration there is just addition of water, the molecule doesn’t break down.
Answer:
It is involved in the conversion of ADP to ATP
Explanation:
Most enzymes in biological systems function by reversible uptake and release of hydrogen in redox processes. The enzyme that catalyses the conversion of ADP to ATP also works by hydrogen ion transfer. Hence H+ is required in photosynthesis for the conversion of ADP to ATP
Answer:
pH = 1.32
Explanation:
H₂M + KOH ------------------------ HM⁻ + H₂O + K⁺
This problem involves a weak diprotic acid which we can solve by realizing they amount to buffer solutions. In the first deprotonation if all the acid is not consumed we will have an equilibrium of a wak acid and its weak conjugate base. Lets see:
So first calculate the moles reacted and produced:
n H₂M = 0.864 g/mol x 1 mol/ 116.072 g = 0.074 mol H₂M
54 mL x 1L / 1000 mL x 0. 0.276 moles/L = 0.015 mol KOH
it is clear that the maleic acid will not be completely consumed, hence treat it as an equilibrium problem of a buffer solution.
moles H₂M left = 0.074 - 0.015 = 0.059
moles HM⁻ produced = 0.015
Using the Henderson - Hasselbach equation to solve for pH:
ph = pKₐ + log ( HM⁻/ HA) = 1.92 + log ( 0.015 / 0.059) = 1.325
Notes: In the HH equation we used the moles of the species since the volume is the same and they will cancel out in the quotient.
For polyprotic acids the second or third deprotonation contribution to the pH when there is still unreacted acid ( Maleic in this case) unreacted.

The primary producer would be at the bottom of the food chain.
