The acid/alkaline balance of a fluid is measured by the pH scale. The scale runs from 0 (extremely acidic) to 14 (extremely alkaline), with pH 7 being neutral. A pH electrode is a sensor that produces a small voltage that is directly proportional to the pH of the fluid in a test chamber. For a certain pH electrode, the proportionality factor is 60 mV/pH. A preamplifier is needed to interface this sensor with a variety of laboratory instruments. The output of the preamp must be 1V when the sensor is immersed in a test solution with pH=4 and 1.75V when it is immersed in a solution with pH=7. Design an amplifier to meet these requirements.
