摘要: Abstract The influence of dissolved HCl on the surface water has been investigated with sum frequency generation (SFG) spectroscopy. Ions in solution cause to be reoriented relative pure water, hydrogen atoms directed toward bulk solution. There is no signal due molecular suggesting that oriented molecules, not HCl, dominate surface. A model proposed account for reported SFG results as well tension and potential measurements. result suggests application Gibbs equation determine excess may need reevaluated.
