The temperature alters for the water was slight while the temperature change for the metal was large. Why was this the case?
If the solution has the same density and specific heat as water, what is ?H for this reaction (per mole of H2O produced)? Assume that the total volume is the sum of the individual volumes.
which produce no significant response to interfering ions. It is then used to measure the pH of 0.0100 M NaOH in 0.50 M NaCl at 25 degrees C. What is the observed pH under these conditions if the true pH is 1.13?
