Ratio of the concentration of the dissociated to the undissociated form?
acid dissociation constant
When was carbonic acid made?
Carbonic acid occurs naturally.
How do you derive pH values for weak acids?
Every acid has a constant, called the acid dissociation constant(or Ka), which shows how much the acid dissociates to form ions in water.For an acid, the general dissociation equation is:HA -------> H+ + A-Ka = (concentration of H+) times (concentration of A-) divided by (concentration of HA)The values for concentrations are the values AT EQUILIBRIUM, where the concentrations of all three substances remain the same.If HA was a strong acid, it would completely(or almost completely) ionize in water to form its ions. Therefore, you can say that the concentration of H+ ions in the solution equal the concentration of HA. From this, you can calculate the pH by using the formula pH = - log (H+).If HA was a weak acid, however, things would be different. The acid only partially ionize in water, so you cannot say that the concentration of H+ is equal to the concentration of HA.If you know the value of the acid dissociation constant, you can easily find the concentration of H+ in the solution, and in turn calculate the pH.You know that the amounts of H+ and A- are equal. If you know the concentration of the acid HA you put in, you can calculate the H+ .
Heating causes a bromthymol blue indicator solution to change yellow to blue rapidly why?
AnswerBromthymol blue is an indicator solution that turns yellow in the presence of carbonic acid (H2Co3). Chemically, water and carbon dioxide combine to form carbonic acid. Heating the solution favors the dissociation of carbonic acid back to carbon dioxide and water and therefore the bromthymol blue returns to its less acidic state and back to it original blue color.Answer$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
Acid formed by mixing water with carbon dioxide?
H2CO3, or carbonic acid, can be formed by dissolving carbon dioxide (CO2) in water (H2O). When carbon dioxide is dissolved in water, carbonic acid "exists in equilibrium" with the water and carbon dioxide; meaning that the carbon, oxygen, and hydrogen atoms involved tend to move around and keep equal concentrations of gas/water mixture and carbonic acid.
What is an acid dissociation constant?
An acid dissociation constant is the equilibrium constant for the disassociation of an acid, ultimately a measure of the acid's strength.
The acid dissociation constant for an acid dissolved in water is equal to?
The strength of an acid or the measure of its tendency to release proton ions (H+) can be indicated from its dissociation constant which is called Ka. The acid dissociation constant, pKa , is the negative logarithm of dissociation constant (Ka).
What is the acid dissociation constant for an acid at equilibrium HX - H X-?
The dissociation constant is:k = [H][X]/[HX]
What is the acid dissociation constant for an acid at equilibrium HX H X?
The dissociation constant is:k = [H][X]/[HX]
Which acid has the greatest acid dissociation constant?
nitric acid.
What is the word equation for the formation of carbonic acid?
The chemical equation for Carbonic Acid is H2CO3.
What is the concentration of undissociated acid if the hydrogen-ion concentration is 0.0001 M and the acid dissociation constant is 0.0000001?
The equation is acid + water equalizes into hydronium and conjugate base, and Ka (acid dissociation constant) is products divided by reactants. If the Acid = (H+)(base)/Ka, then the acid concentration is (H+)(H+)/Ka, or (0.0001)(0.0001)/0.0000001, which equals 1M.
The acid dissociation constant for an acid dissolved in water is equal to the?
Z
The abbreviation Ka represents?

Factors affecting dissociation constant of acid?
Temperature
What does the abbreviation Ka represent?

What will a strong acid have more of when compared to a weak acid?
The strong acid has a higher dissociation constant.
