WebWhey as a by-product from the manufacture of hard, semi-hard or soft cheese and rennet casein is known as sweet whey and has a pH of 5.9 – 6.6. Manufacture of mineral-acid precipitated casein yields acid whey with a pH of 4.3 – 4.6. Table 15.1 shows approximate composition figures for whey from cheese and casein manufacture. WebpH is a logarithmic scale. A solution that has a pH of 1.0 has 10 times the [H +] as a solution with a pH of 2.0, which in turn has 10 times the [H +] as a solution with a pH of 3.0 and so forth.. Using the definition of pH, it is also possible to calculate [H +] (and [OH −]) from pH and vice versa.The general formula for determining [H +] from pH is as follows:
