Question

For 0.3513 M KNO3 what is the pH for the two possible definitions of pH? For the
concentration definition of pH you should ignore activity (i.e., solve in the usual way). The size
parameter for hydrogen ion is 0.900 nm and for hydroxide is 0.350 nm. Use Kw=10−14 for both
methods, but in concentration units for the concentration-based pH and in activity units for activity
based pH.

A thermostat is a component which senses the temperature of a physical system and performs actions so that the system's temperature is maintained near a desired setpoint.
