Phosphate-buffered saline (PBS) is a solution commonly used in studies of animal tissues and cells. Its composition is 137 mM NaCl, 2.7 mM KCl, 10 mM Na₂HPO4 (pK₁ = 2.14), and 1.8 mM KH₂PO4 (pKa = 6.86). Calculate the pH and osmolarity of PBS. Give the osmolarity in units of osmoles per liter (osm/L). pH = Enter numeric value osmolarity = osm/L
