Answer:
The pH of the solution lies from 11 to 12.Hence, option e is correct.
Explanation:
The value of for caffine =
Initial
0 0.01 M 0
AT equilibrium:
x (0.01 -x)M x
Solving for x:
x = 0.0096 M
The pOH of the solution is given by :
pOH = 2.02
pH= 14 - pOH = 14 - 2.02 = 11.98
The pH of the solution lies from 11 to 12.
The question is: 10 g of carbonic acid H2CO3 are dissolved in 150 g of water. Determine the% m / m concentration of that solution?
Answer: The% m / m concentration of that solution is 6.66%.
Explanation:
Given: Mass of solute = 10 g
Mass of solvent = 150 g
Formula used to calculate the %m/m is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that the% m / m concentration of that solution is 6.66%.
Answer:
A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. At the same concentration, weak acids have a higher pH value than strong acids.
