Phosphoric acid or orthophosphoric acid (H₃PO₄) is triprotic acid, which means it lose three protons in chemical reaction (in reaction of esterification with alcohol) and sulfuric acid (H₂SO₄) is diprotic acid, which means it lost two protons in chemical reaction and does not have enough palce to bind alcohol.
Answer: burning paper
Explanation:
The paper burns in air to form smoke and ash. which makes it a chemical change.
Answer:
The transmittance is the amount of energy that a body goes through in a certain amount of time without being absorbed and the absorbance is the amount of light that is absorbed by a solution.
There is no difference between absorptivity and molar absorptivity because the two terms express the same idea, because molar absorptivity is the absorbance of a solution per unit path length and concentration, so that the absorbance is proportional to concentration.
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.
