Chemistry buffer
WebA buffer solution is prepared by adding 0.125 mol ammonium chloride to 500. mL of 0.500-M aqueous ammonia. Calculate the pH of the buffer. If 0.0100 mol HCl gas is bubbled into 500. mL buffer and all of the gas dissolves, calculate the new pH of the solution. 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.

Yes, the pH of the blood is controlled by the bicarbonate buffer system: CO₂ (g) + H₂O (l) ⇌ H₂CO₃ (aq) ⇌ H⁺ (aq) + HCO₃⁻ (aq) If the concentration of CO₂ temporarily gets too high, the ability of the buffer to control pH may be temporarily overloaded.
