How many equivalent OH-1 are there in HC2H3O2?
There is only one equivalent of OH^-1 in one molecule of HC2H3O2.
How do you neutralize HC2H3O2 plus LiOH?
Use equimolar quantities: LiOH + HC2H3O2 (acetic acid) --> C2H3O2- (acetate) + Li+ + H2O
0.15M solution of weak acid HA has pHof 5.35 What is Ka?
To calculate the Ka value of the weak acid HA, you can use the pH of the solution and the formula for calculating the Ka. First, calculate the concentration of [H+], which is 10^(-pH). Then, use the expression for Ka: Ka = [H+][A-]/[HA], where [A-] and [HA] are assumed to be equal in a weak acid solution. Plug in the [H+] value you calculated and the initial concentration of HA to find Ka.
Could KB for a weak base be determined the same way the Ka for a weak acid is determined?
No, the Kb for a weak base is determined using the equilibrium constant expression for the reaction of the base with water to produce hydroxide ions. It is not the same as determining Ka for a weak acid, which involves the equilibrium constant expression for the dissociation of the acid in water.
How we calculate the ka from the original equation?
To calculate the acid dissociation constant (Ka) from the original equation, you can use the equilibrium expression that represents the dissociation of the acid and the concentrations of the products and reactants at equilibrium. Ka is equal to the concentration of the products divided by the concentration of the reactants at equilibrium. This value can provide information about the strength of the acid.
What is the pH of 0.2 M acetic acid ka equals 1.8 x 10-5?
What is the pH of 0.2 M acetic acid Ka equals 1.8 x 10-5? This is an equilibrium problem.When HC2H3O dissolved in water, it forms H3O+1 ions and C2H3O2-1 ions. As the H3O+1 ions and C2H3O2-1 ions bounce around in the water, they reform water and HC2H3O2 molecules.#1 HC2H3O2 + H2O = H3O+1 + C2H3O2-1Ka is the dissociation constant. The dissociation constant is a measure of the number of number of H3O+1 and C2H3O2-1 ions per liter of solution compared to the original number of HC2H3O2 molecules per liter of solution. The brackets [ ] mean moles/liter, which is a measure of the concentration of the substance inside the brackets..#2 Ka = [H3O+1] * [C2H3O2-1] ÷ [HC2H3O2], is the dissociation constant equation.When one molecule of HC2H3O2 dissociates, in water, it forms one H3O+1 ion and one C2H3O2-1 ion.A 0.2 molar solution of HC2H3O2 means 0.2 moles of HC2H3O2 was dissolved in enough water to make one liter of solution#1 HC2H3O2 + H2O = H3O+1 + C2H3O2-1#2 Ka = ( [H3O+1] * [C2H3O2-1] ) ÷ [HC2H3O2]We do not include the concentration of water, because the number of water molecules that do not dissociate greatly exceeds the number that do dissociate. We know this because the Ka is very small.Since we do not know how many HC2H3O2 dissociated, let x equal the moles/per liter of HC2H3O that dissociated forming x moles/per liter of H3O+1 ions and x moles/per liter of C2H3O2-1 ions. Now, substitute x for the [H3O+1] and. [C2H3O2-1].#3 Ka = x * x ÷ [HC2H3O2]#4 Ka = x^2 ÷ [HC2H3O2]#5 x^2 = Ka ÷ [HC2H3O2]#6 x = ( Ka ÷ [HC2H3O2] ) ^0.5Now, substitute Ka = 1.8 x 10-5 for the dissociation, and 0.2 for [HC2H3O2].Solve for the value of x.(You can substitute these values of Ka and [HC2H3O2] into equation #3 and solve for x. I just wanted to show you how to derive the equation.)This answer will be very small, around n x 10^-3.x = [H3O+1] = about 10^-3.pH = - log of the [H3O+1]pH = - log xDon't forget the negative sign.This answer will be between +2 and +3In case you do not know how to do pH problems, I will do an example.What is the pH of 0.1 molar solution of HOBr? (Ka = 2.0 x 10^-9Eq.#1 HOBr + H2O = H3O+1 + Br-1Eq.#2 Ka = ( [H3O+1] * [Br-1] ) ÷ [HBr]Eq.#3 Ka = x * x ÷ [HBr]Eq.#4 Ka = x^2 ÷ [HBr]Eq.#5 x^2 = Ka ÷ [HBr]Now, substitute Ka = 2.0 x 10^-9 for the dissociation, and 0.1 for [HBr].(10^-1)Solve for the value of x.Eq.#5 x^2 = (2.0 x 10^-9) ÷ (10^-1)Dividing powers, means subtracting exponents!! (-9) - (-1) = -8Eq.#5 x^2 = (2.0 x 10^-8)Remember, when you take (n * 10^-8)^0.5 = n^0.5 * (10 ^-8)^0.5Remember, when you take the square root of 10^-8, you get 10^-4, because 10^-4 * 10^-4 = 10^-8Eq.#6 x = (2.0 x 10^-8) ^0.5=x = [H3O+1] = 1.414 * 10^-4pH = - log of the [H3O+1]log 10^x = exponent of 10 = xLog of ( n * 10^-b) = (log n) + (-b)pH = - log (1.414 * 10^-4 )pH = (- log 1.414 + -log * 10^-4 ) = (-0.15) + (+4) = +3.85Don't forget 2 negatives = a positive +4This answer will be between +3 and +4
What is the Conjugate base of HC2H3O2?

What are the solution properties between HCL and hc2h3o2?
Hydrochloric acid (HCl) is a strong acid, while acetic acid (HC2H3O2) is a weaker acid. In solution, HCl will dissociate completely into H+ and Cl- ions, while HC2H3O2 will only partially dissociate. This results in a higher concentration of H+ ions in HCl solution compared to HC2H3O2 solution at the same concentration.
Get a life in tagalog?
This expression is rarely used in Tagalog and that this one don't have exact equivalent expression in the language. Anyhow, we can use alternative expressions for this like "Umayos, ka" or "Pwede kang magbagong buhay" or simply "ayusin mo buhay mo" or "magbagong buhay ka nga".
