Because the potential of pH electrodes can vary, it is necessary to CALIBRATE a pH electrode before use. For many uses, a two-point calibration procedure is appropriate. This involves the use of a solution buffered at pH ______to set the intercept and a solution buffered at pH_____to set the slope.
To treat a burn on your hand, you decide to place an ice cube on the burned skin. The mass of the ice cube is 12.9 g, and its initial temperature is -13.9 °C. The water resulting from the melted ice reaches the temperature of your skin,
