Answer:
The value of n in the hydrate formula is 5 ,.
Explanation:
Mass of hydrate of copper sulfate = 14.220 g
Moles of hydrate of copper sulfate =
Mass of copper sulfate after heating = 8.9935 g
Moles of copper sulfate =
Solving for n, we get:
n = 5
The value of n in the hydrate formula is 5 ,.
Answer:
C. pH values are different because the solution partially ionizes and the HCl solution ionizes 100 percent.
Explanation:
Strong acids are the acids which completely ionizes in the solution while weak acids are the acids which ionizes partially in the solution. They exists in equilibrium in the solution with their respective ions.
Thus, strong acids furnish greater concentration of protons as compared to weak acid when same concentration of both types are taken.
<u>Also, pH is the negative of the logarithm of the hydrogen ions. Thus, hydrogen ion concentration for both acids are different and thus pH will be different.</u>
