WebAll over the concentration of acetic acid at equilibrium. That's one minus X. So I put in here 1.00 minus X and this is equal to the Ka for acetic acid. So we have that on our table above. Let's go back up here to the table that we talked about earlier and here is the Ka for acetic acid. 1.8 times 10 to the negative five. WebA larger K a indicates a greater ratio of ions (including hydronium ions) to uncharged acid. Therefore, a larger K a indicates a stronger acid. For example, the larger K a for chlorous acid (1.2 × 10-2) compared to acetic acid (1.8 × 10-5) tells us that chlorous acid is stronger than acetic acid. fast markets chicago market index prices

WebThe room temperature was given as 25°C. For the acetic acid solution, the Ka calculation for the 0.3M solution is calculated by using the equilibrium expression: Ka = [H+] [CH3COO-]/ [CH3COOH]. The initial concentrations of the reactants and products are given, and the change in concentration is calculated as the initial concentration minus ... WebNow acetic acid is a weak acid and weak acids don't donate protons very well. So acetic acid is gonna stay mostly protonated. When you think about this reaction coming to an equilibrium, you're gonna have a relatively high concentration of your reactants here. When we write the equilibrium expression, write KA is equal to the concentration of ...
