What is the equilibrium constant for the dissociation of acetic acid in water?
The equilibrium constant for the dissociation of acetic acid in water is known as the acid dissociation constant (Ka) and is approximately 1.8 x 10-5.
What is the equilibrium constant for acetic acid in a chemical reaction?
The equilibrium constant for acetic acid in a chemical reaction is a measure of the ratio of products to reactants at equilibrium. It is denoted by the symbol K and represents the balance between the forward and reverse reactions of acetic acid.
Does all of the acetic acids dissociate after the reaction reaches equilibrium?
In a chemical reaction involving acetic acid, not all of the acetic acid molecules will dissociate completely, even at equilibrium. This is because acetic acid is a weak acid and only partially dissociates into ions in solution.
The fraction of acetic acid molecules ionized in solution?
The fraction of acetic acid molecules ionized in solution can be calculated using the equation for the dissociation constant (Ka) of acetic acid. It is equivalent to the concentration of the ionized form (CH3COO-) divided by the total concentration of acetic acid in the solution. This is typically a small percentage for weak acids like acetic acid.
At a certain temperature a 0.12 m solution of acetic acid ch3cooh has a pH of 3.0 what is the ka of ch3cooh at this temperature?
Given that the pH of a 0.12 M solution of acetic acid (CH3COOH) is 3.0, you can calculate the concentration of H+ ions in the solution using the formula pH = -log[H+]. Once you have the concentration of H+ ions, you can use it to calculate the concentration of CH3COO- ions using the ionization constant expression for acetic acid (CH3COOH) and then determine the Ka value.

What is the molar mass of acetic acid by elevation of boiling point method?
The molar mass of acetic acid can be determined using the elevation of boiling point method by measuring the change in boiling point of a solution of acetic acid relative to the boiling point of the pure solvent. By applying the equation ΔT = K_b * m, where ΔT is the change in boiling point, K_b is the ebullioscopic constant of the solvent, and m is the molality of the solution, the molar mass of acetic acid can be calculated using the formula MM = (RT2) / (K_b * ΔT), where MM is the molar mass of acetic acid, R is the gas constant, and T is the temperature in Kelvin.
A 0.20 mol L of both acetic and acid and sodium acetate has a pH of?
The pH of a solution containing 0.20 mol/L of acetic acid and its conjugate base, sodium acetate, depends on the specific concentrations of the acid and its conjugate base, as well as the ionization constant (Ka) of the acid. To calculate the pH, you need to set up an equilibrium expression and solve the equation.
If 0.1MHAC is titrated with 0.1MNaoh and the dissociation constant ka of acetic acid is 1.8210-5 and the solubility product of water is 110-14 what is the initial pH of the acid?
To find the initial pH of the acetic acid solution, you would need to use the dissociation constant (Ka) of acetic acid. The initial pH of acetic acid can be calculated using the formula pH = 0.5 * (pKa - log[C]), where pKa is the negative logarithm of the dissociation constant and [C] is the initial concentration of the acid. With the given Ka value of 1.82 x 10^-5 for acetic acid, you can determine the initial pH of the solution.
What happens if exactly 0.3 equivalent of base is added to a solution of fully protonated acetic acid (pKa 4.76)?
When 0.3 equivalents of base are added to a solution of fully protonated acetic acid, which is predominantly in its protonated form (CH₃COOH), the base will deprotonate some of the acetic acid, forming acetate ions (CH₃COO⁻). Since the pKa of acetic acid is 4.76, the addition of the base will shift the equilibrium towards the formation of acetate. The resulting solution will contain a mixture of acetic acid and acetate, leading to a buffer system that can resist pH changes. The pH of the solution will increase, but it will remain below the pKa, indicating that acetic acid is still the predominant species.
What is the 1M acetic acid?
Add 60g of Glacial Acetic Acid to a 1 liter volumetric flask. Make up to the mark with deionized water. The result is 1M acetic acid solution.
How do you get a 5 percent diluted acetic acid from a 99 percent acetic acid solution?
To make a 5% diluted acetic acid solution, you would mix 1 part of the 99% acetic acid solution with 19 parts of water (since 1 part acetic acid solution + 19 parts water = 20 parts total solution, and 1/20 = 5%). This will result in a 5% acetic acid solution.
What is the molarity of a formic acid solution HCOOH(aq) that has the same pH as 0.259 M CH3COOH(aq)?
To find the molarity of a formic acid solution (HCOOH) that has the same pH as a 0.259 M acetic acid solution (CH3COOH), we first need to determine the pH of the acetic acid solution. The dissociation of acetic acid can be approximated, and since it is a weak acid, we can use its dissociation constant (Ka) to find the concentration of hydrogen ions. Assuming similar dissociation behavior, HCOOH's molarity can be estimated using its own dissociation constant, which is slightly higher than that of acetic acid. Thus, the formic acid solution is expected to have a molarity slightly less than 0.259 M to achieve the same pH.
