To answer this question,you have to know the molecular geometry of the compound. The molecular geometry is empirical for certain compounds. For H₂O, the bond angle is 109.5°. On the other hand, the bond angle for H₃O⁺ is between 104.5° and 109.5°. <em>So, the smaller bond angle would be H₃O⁺</em>.
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>
I hope it helps!
Single replacement or single displacement reactions
Explanation:
In a single replacement or displacement reaction, the activity series is useful in predicting whether the reaction will take place or not.
- In this reaction type, one substance is replacing another.
C + DE → CD + E
- The relative positions of the two elements in the activity series provides the driving force for the single replacement reaction.
- An element high up in the series will displace one that is lower in the series because it is more reactive.
