Answer:
pH = 6,951
Explanation:
The neutral form of aspartic acid is in its isolectric point. For aspartic acid the isoelectric point is the average of pka1 and pka2, thus:
= 2,945
The addition of stoichiometric amounts of NaOH at the first equivalence point will increase the pH at average of pka2 and pka3 thus:
= 6,951
Thus, <em>pH at the first equivalence point is 6,951</em>

Weight = mass x gravitational acceleration = mg
m = 10kg
g = 9.8 m/s^2
So, weight = 10 x 9.8 =

Any mixture that looks the same through the substance is homogenous. The different parts are unable to be visibly seen. (Any periodic element is homogenous)
Any mixture that can be easily determined a mix and cannot be evenly separated or dispersed is heterogenous.
