Find concentration from pka
WebWe can construct an acid dissociation expression for strong acids and calculate their Ka and pKa values. These values indicate that the products of a strong acid reaction are … WebTo find the pKa of acetic acid, we take the negative log of the Ka value. So the negative log of 1.8 times 10 to the negative fifth is equal to 4.74. ... So whenever the concentration …

WebKa = 10 (-pKa) When pKa is a whole number, such as -7, this operation is easy to perform, but when it contains a fraction, such as 7.5, you may have to look up the value in a table. … WebAll steps. Final answer. Step 1/4. 2. To calculate the pH of the acid at the concentration calculated in Question 1, we first need to determine the amount of moles of NaOH used in the titration : moles NaOH = M × V = 0.25 mol / L × 0.01354 L = 3.385 × 10 − 3 m o l. Since the acid and the base are in a 1:1 ratio at the equivalence point ...
WebThe same information is provided by pKa, but in a different format. The stronger the acid, the lower the pKa value. Alternatively, the weaker the acid, the higher the pKa value. The pKa value of weak acids is usually between 2 and 14. Converting From pKa to Ka. The conversion of pKa to Ka is given below. pKa = – log Ka – pKa = log Ka. 10 ...
