Answer:

The structures are shown in figure.

Explanation:

At low pH (pH < 1.88) aspartic acid is completely protonated.

Both amine and carboxylic groups are protonated.

At medium pH (3.65-9.68) amine group is protonated and both the carboxylic groups are deprotonated.

At high pH (above 9.68) all the groups are deprotonated.

Brilliant_brown [7]

Answer:

Explanation:

THE CORECT QUESTION

A 50.0 mL solution of 0.127 M KOH is titrated with 0.254 M HCl. Calculate the pH of the solution after the addition of each of the given amounts of HCl.

SOLUTION

Get the concentration of the HCl first using titration formula

CA X V A / CB VB = NA/ NB

Equation of reation; KOH + HCl => KCl + H2O

CA = 0.254 M

CB = 0.127

VA = 1/0.254 = 3.937

CA (after the addition) = 0.127 x 50 / 3.937

                                     = 1.612 M

But pH = - Log[hydrogen ion]

            = -log 1.612

            =

Describe how the mass of the product can be calculated when one reactant is in excess
kvasek [131]
On the off chance that one of the reactants is in overabundance yet you don't know which one it is, you have to compute the hypothetical item mass for the both reactants, with a similar item, and whichever has the lower yield is the one you use to precisely depict masses/sums for the condition, since you can't have more than the non-abundance reactant can create.

why is it essential to know the water temperature in this experiment- to find the vapor pressure of the water
Oksi-84 [34.3K]

Answer:

Vapour pressure of a liquid varies with temperature

Explanation:

The vapour pressure of any liquid is directly proportional to the temperature of the liquid. This implies that, as the temperature of the liquid increases, the vapour pressure increases likewise and vice versa.

Since the vapour pressure of liquid varies with the temperature of the liquid, it is essential to know the water temperature in the experiment to determine the vapour pressure of water.
