Hmm... I'm unsure but its either B or D.
Answer:
It is either c or d. Hope this helps. Please tell me if I was right or wrong.
Explanation:
Answer:
Overall charge on protein becomes increasingly positive as pH decreases while overall charge on protein becomes negative as pH increases.
Explanation:
It is noticeable that protein are made up of amino acids which contain amine and Carboxyl functional groups.
Protein molecules in aqueous solution become positively charged (Protonated) as pH drops because of the fact that carboxylic acids become less negatively charged as the pH goes on to drop while amine become more positively charged.
Whereas overall charge on protein becomes more negative as pH increases because Acidic groups become more negatively charged while the basic group become less positively charged.
Answer:
The pH range, reaction rate, accuracy and solubility are affected by the temperature.
Explanation:
Hello,
Temperature is factor affecting how solutions behave, thus, it could modify the pH range (change in color values) for an indicator in the presence of a base or an acid, since the kinetics behind the change of color is modified maybe decreasing or increasing the aforesaid range. Next, temperature usually increases the reaction rate, that's why the change in color could become faster or out of the proper change range. Then, in titration we use temperature-sensitive glassware which could expand due to high temperatures and subsequently turning out into wrong measurements. Finally, solubility is affected by the temperature, since the molecules are allowed to interact more effectively, that's we must make sure that they're completely dissolved at room temperature while titrating.
Best regards.
