Therefore, pKa was introduced as an index to express the acidity of weak acids, where pKa is defined as follows. ... In addition, the smaller the pKa value, the stronger the acid. For example, the pKa value of lactic acid is about 3.8, so that means lactic acid is a stronger acid than acetic acid.

WebAug 14, 2016 · That is only half the story. It is about the strength of the H-Br versus H-I bond. Since I is larger than Br, the H-I bond is longer, weaker, and therefore more prone … WebThe pka values of HF, HCI, HBr and HI are 3.2, -7.0, -9.5 and -10.0, respectively. HF is the strongest acid because it etches glass. HF is the weakest acid because it has the … WebJul 23, 2024 · At 25 degrees Celsius the Ka value for acetic acid is equal to 1.8 times 10 to the negative fifth. The Ka value is less than one because acetic acid is a weak acid. To 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. origins of the silk road
