WebWhat is the concentration of a solution formed by diluting 25.0 mL of a 3.2 M NaCl solution to 135.0 mL? M1V1=M2V2 (3.2M)(25.0mL)=M2(135mL) ( mL to L) then divide by V2 =.59M NaCl Which species is the conjugate acid of HCO3-? WebIf 1 mL of stomach acid [which we will approximate as 0.05 M HCl (aq)] is added to the bloodstream, and if no correcting mechanism is present, the pH of the blood would go from about 7.4 to about 4.9—a pH that is not conducive to continued living. Fortunately, the body has a mechanism for minimizing such dramatic pH changes.
