What is the pH of 0.01 m ch3cooh?
5.0
The pH of 0.01 M solution of acetic acid is 5.0.
What is the pH of 0.1 m of CH3COONa?
8.9
Neglecting [H+], the mass balance equations give [CH3COO ] + [CH3COOH] = 0.1 [CH3COOH] = [OH ] + [HCO3 ] Without carbonic acid we get [CH3COOH] = [OH ] and [CH3COO ]=0.1; then[OH ]2 = 0.1×10 9.24 and pH = 8.9.
What will be the pH of 0.01 M?
Hence, the answer is – option (d) – the pH of 0.01 M solution of HCl is 2. =>pOH = 14 – pH. Note: “pH is a scale used to specify the acidity or basicity of an aqueous solution.
What is the pH of ch3coo-na+ and NaOH?
Now the mixture will acts as a salt CH3COO-Na+ of week acid CH3COOH and strong base NaOH. Then pH is 7 + 0.5* (pKa+ logX) here X is concentration of salt. Now both are equal volumes and concentrations. Here we need volume of acid CH3COOH and base NaOH.
How do you find the concentration of CH3COOH in water?
When CH3COOH is placed in water, a small fraction of the acid dissociates to CH3COO- and H3O+. Thus at equilibrium, you get x molar CH3COO-, x molar H3O+, and (0.1-x) molar CH3COOH. Using the Ka of the acid, you can have the expression: take note that the concentrations should be those found after establishing equilibrium.
What is the Kaka for CH3COOH?
Ka for CH3COOH = 1.8*10^-5 ( this must be given to you – you do not need to remember it. Or you must be able to look this up in a reference list)
What is the pH of acetic acid in water?
Acetic acid is a weak acid and in water only partially dissociates and by the equation shown below. The pKa of acetic acid is 4.76, Ka = 1.74 * 10^-5. So, you have to solve the following to determine ‘x’. The pH of mixture of 0.01 M HCl and 0.1 M CH3COOH is approximately equal to? CH3COOH is a weak acid that does not dissociate to a great extent.
