Document Summary

Any change in the concentration of h+ will affect the activity of almost every cell. Hydrogen atom has a single proton (positive charge) and a single electron (negatively charged)= electrically neutral. The hydrogen ion (h+) has lost its electron leaving only the positively charged proton. An acid is any molecule that will release h+ when put in solution i. e hcl will break apart into h+ and cl- The presence of the free h+ is what makes a solution acidic. A strong acid will dissociate rapidly and release large amounts of h+ in solution. A base is any molecule that will accept an h: bicarbonate ions (hco3-) will bind with h+ to form carbonic acid (h2co3) Bases lower the concentration of free h+ by combining with the h+ With less free h+, the acidity of the solution will decrease and become more basic or alkaline. Way of quantifying the conc of h+ in any solution.
