24.08.2009  · Interestingly enough, though, the hydrochloric acid in stomach acid is at a concentration of about 0.1 M. If you dilute reagent grade HCl to 0.1 M and dip your finger into it, it shouldn’t hurt (unless you have an open wound in which case it will hurt like crazy, or your skin is sensitive). At this level of dilution, it is referred to as an "irritant", not "corrosive". However, stomach fluids.

acid is fully ionized. From the equation, the molar concentration of OH − is 10 −13. For a 0.1 M solution of NaOH, the OH − is 0.1 M , but the hydrogen ion concentration is 10 −13.

The relationship between acid strength and the pH of a solution. Typical concentrations of these ions in solution can be very small, and they also span a wide range. [How do you do logarithm calculations?]. this to a very diluted strong acid (like 1 drop of HCl in a swimming pool) then the pH of the weak acid will be.

pH is defined as pH = pH = -log 10 [H + ] It is explicitly a measure of the concentration of hydrogen ions inan aqueous solution which also indicates how acid or basic thesol. ution is.

Using the balanced chemical equation, we see that there is a one-to-one ratio of moles of HCl to moles of NaOH. stomach acid, HCl, 0.10. It is also possible that 2 h was an inadequate time period for gastric emptying and that some minerals may have.
