Buffer solution can be prepared by
WebThe function of a buffer is to keep the pH of a solution within a narrow range. As you can notice from the above equation, the ratio of [HA]/[A-^\text{-}-start superscript, start text, negative, end text, end superscript] directly influences the pH of a solution. In other words, the actual concentrations of A- and HA influence the effectiveness ... 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. arrow_forward.
