Estimate pH value of the following solutions in pure water: 1. 0.02 M HCl 2. 0.005 M Ba(OH)2 3. 0.00005 M H2SO4 4. 10-9 M HClO4 5. 0.030 M NaCl 6. 0.01 M NaOH 7. 0.01% ethanol 8. 10^-10 M KOH
Estimate ωc for water molecules in liquid water at 17 ◦ C, given that m = 3.0 × 10−26 kg. Remember that the number of states is VrVp/h^3. For an estimate of the accessible volume in momentum space, assume that the maximum magnitude of the momentum for any molecule is roughly equal to the root mean square value; most accessible states reside within a sphere of that radius in momentum space. Assume that any one molecule can go anywhere within...
