WebSo the Ka is equal to the concentration of the hydronium ion. And since there's a coefficient of one, that's the concentration of hydronium ion raised to the first power, times the concentration of the acetate anion also raised to the first power, divided by the concentration of acidic acid raised to the first power. WebSince the acid and the base are in a 1:1 ratio at the equivalence point, the amount of moles of the acid is also 3.385 × 10 − 3 m o l. We can use this value to calculate the concentration of the acid: C = n V = 3.385 × 10 − 3 m o l 10.00 m L = 0.3385 mol / L View the full answer Step 2/4 Step 3/4 Step 4/4 Final answer Transcribed image text: 2.
Calculate one concentration using Ka - YouTube
WebKa from pH We can use pH to determine the Ka value. pH is a standard used to measure the hydrogen ion concentration. pH = – log [H + ] We can rewrite it as, [H +] = 10 -pH. If … WebThe concentration is indicated by the square brackets. The equation is simplified by keeping the concentration of water constant unless the acid is sufficiently concentrated: … state of michigan governor news

WebIn that same sense, Ka * Kb can be conceived as multiplying the products of both Ka and Kb and dividing by the reactants of both Ka and Kb. Reverse the process you use for writing equilibrium expressions: multiplication = add to the products, division = add to … WebClearly, ka =/ 1/Kb : one has H3O+ and the other has OH- (the others are in the equation, but in very very very small quatities so we ignore them) For example, HCN is an acid and … WebMay 4, 2024 · You can easily calculate the H + ion concentration using the formula [H +] = 10 -pH.
