BSC 2010C Chapter Notes - Chapter 3: Hydrophile, Surface Tension, Heat Capacity
Document Summary
High heat of vaporization takes a lot of energy to convert water as a liquid into a gas. Water expands when frozen, it captures air which is why it is less dense and floats. Acid substance that increases h+ ions in a solution. Base substance that accepts h+ ions or donates oh- ions in a solution; reduces h+ concentration. Ph = the negative log of the h ion concentration; ph declines as h ion concentration increases and ph rises as h ion concentration decreases. Scale is logarithmic, for every unit of inc/dec, the ion concentration changes by factor of 10: goes from 0-14, 7 = neutral; <7 is acid, >7 is basic. Buffers moderate changes in ph they accept excess h ions and donate h ions when depleted. Normal rain = ~5. 6, anything under is acid rain.
