WebA buffer is basically a high-impedance device that accepts a voltage input and outputs the same voltage as output. The advantage of a buffer is that it has a high input impedance. Why is a high input impedance … WebBuffer, as we have defined, is a mixture of a conjugate acid-base pair that can resist changes in pH when small volumes of strong acids or bases are added. When a strong base is added, the acid present in the buffer neutralizes the hydroxide ions (OH ^\text {-} - ). WebBuffers typically consist of an acid-base pair, with the acid and base differing by the presence or absence of a proton (a conjugate acid-base pair). For instance, one of the buffers that maintain the pH of human blood involves carbonic acid (H _2 2 CO _3 3) and its conjugate base, the bicarbonate ion (HCO _3 3 ^- − ). high temperature industrial heat pumps
