Agricultural soils in California are high in salt content (assume NaCl). Irrigation water used in growing row crops in CA must be filtered before discharge in rivers and streams, and is typically performed by using reverse osmosis (RO). The water quality standard in CA for salt in ag runoff water is 2.00 parts per thousand (ppt). If irrigation runoff is 58.08 ppt, what applied (hydrostatic) pressure must be used to filter runoff by RO to meet the CA water quality...

The average person adds roughly 14 grams of NaCl (58.4 g/mol) to 3.5 L of water when cooking pasta. This increases the boiling boint of water. We know that the rates of reaction are related to temperature. What is the relative rate of pasta cooking in pure boiling water, boiling salt water (14 g / 3.5 L), and boiling saturated aqueous NaCl solution?
