Now take the antilog of both sides. On a hand calculator, look for an inverse key, or an ex key. If the calculator has an inverse key, enter (0.3612, press inverse, then ln. The result will be 0.6969, the antiln of (0.3612. To use the ex key, press ex, enter (0.3612, and press equals. The result of e(0.3612 = antiln((0.3612 = 0.6969. Thus = 0.6969

Ka = antilog ( ) = Find the Ka of Alizarin Yellow: Thymol Blue (A diprotic Indicator) You’ll notice that Thymol Blue appears twice on the Indicator Table: This is because Thymol Blue is a diprotic acid. Each time it loses a proton, it goes through a color change. We can call Thymol Blue (Tb) a weak acid H2Tb

Ans: (1) pKa = –log Ka. (2) See Fig. 2-17, p. 59; pKa is the value of pH at the inflection point in a plot of pH vs. extent of titration of the weak acid. At the pKa, the concentration of ionized acid equals the concentration of un-ionized acid.

LOGARITHM is an exponent. It is the exponent to which the base must be raised to produce a given number. For example, what is the answer here? 23 = _, then 3 is called the logarithm of _ with base 2.We could also write this 3 = log2_, where 3 is the exponent to which 2 must be raised to produce _. We write the base as a subscript. Since 10

pH = -log[H3O+] We use the negative log so pH is always positive. Examples: [H3O+] = 1 x 10-3 [H3O+] = 6.3 x 10-8. pH = -log[1 x 10-3] pH = -log[6.3 x 10-8] pH = 3.0 pH = 7.20. The smaller the pH, the more acidic the solution. A solution with a [H3O+] of 10-1M - a strongly acidic solution - has a pH of 1.

* On some calculators, you press the LOG key before the number, and on some you press the number then the LOG key. Example (HP-11C) Your calculator How is the log10 key labeled? LOG (in blue). It is g-shift 10x How is the base 10 antilog key labeled? 10x. To take the log10 of 1000 which do you enter first, the number or the LOG key? The number.

If x = log b, then antilog (x) = b. Antilog table for base 10 is readily available. Antilog tables are used for determining the inverse value of the mantissa. From the characteristic, the position of the decimal point can be determined. Antilog tables consist of rows that go from .00, . 01, up to .99. The columns have values 0,1, 2, up to 9.
