WebIn shampoos. Many shampoos use a citric acid/sodium citrate shampoo to maintain a slightly acidic "pH balance". This counteracts the basicity of the detergents present in the shampoo. In baby lotions. Baby lotions are buffered to a pH of about 6. This hinders the growth of bacteria within the diaper and helps prevent diaper rash. WebHowever, when using this method you have to remember that the desired pH of the buffer solution has to equal the pKa of the weak acid. The question states that the pKa of the acid is 5.9 and the desired pH of the buffer is 3.5; therefore, it is not possible to make the buffer with the given acid. group 4 junior assistantWebAcid-balance balance is measured using the pH scale, as shown in Figure 26.4.1.

WebBuffers are broadly divided into two types – acidic and alkaline buffer solutions. Acidic buffers are solutions that have a pH below 7 and contain a weak acid and one of its salts. For example, a mixture of acetic acid and sodium acetate acts as a buffer solution with a pH of about 4.75. Alkaline buffers, on the other hand, have a pH above 7 ... WebApr 2, 2024 · The blood maintains its pH of ~7.4 primarily by the carbonic acid/hydrogen carbonate buffer system. The blood pH in the range of 7.45 to 7.35 is considered healthy, but outside of this range causes medical problems. If the blood pH decreases to 6.8 or increases to 8.0, death may occur.
