We propose explicit and implicit approaches for the teaching of acid-base chemistry based on research into the history and nature of science (NoS). To supp
base produces water plus a salt. Carboxylic acids with six or fewer carbon atoms are freely or moderately soluble in water; those with more than six carbons are slightly soluble in water. Soluble carboxylic acid dissociate to an extent in water to yield hydrogen ions. The pH of solutions of...
At the physiological pH of 7.4, phosphate exists in the plasma as a ratio of [HPO42−]: [H2PO4−] ~ 4:1. While most of the Pi in the plasma is free, approximately 10% is protein bound and 5% is complexed with sodium, calcium, and magnesium. 90–95% of the plasma phosphate ...
