The answer to this question would be because reaction that joining sugar will produce a water molecule.
The condensation reaction is a reaction that will combine two or more molecule and produce a small molecule like water. Reaction to create disaccharide(lactose, sucrose) sugar will need two monosaccharide sugar molecule and produce a bigger sugar(twice as big) and water.
Answer:
hydroxide ion would be the answer
The acid dissociation constant(Ka) is 0.0095
The reaction for this dissociation of acid is
HSO4 ⇄H+ + SO4 -2
The dissociation constant can be determined from the following expression
[H+] = 10-PH
= 10-1.35
[H+] = 0.0447
[H+] = 0.0447 mol / L
From equation, [H+] = [SO4-2] = 0.0447 mol / L
[SO4-2] = 0.0447 mol / L
From the values of [H+], [SO4-2] and [HSO4] Ka can be calculated as follows,
Ka = 0.0447 * 0.0447 / 0.200
= 0.0019 / 0.200
= 0.0095
Hence the value of the acid dissociation constant (Ka) for the given reaction is 0.0095
