  1. Return to "Home" screen
  2. Access "Units" screen to change prefered units
  3. Recall the saved (preferred) units
  4. Save Calculation
  5. e-mail calculation inputs and results
  6. Share screen capture
  7. Enter HCl acid concentration
  8. Enter HCl acid solution volume required
  9. Select the solution unit measurment  "Molarity or Normality"(☆)
  10. Enter the desired Molarity/Normality value
  11. The calculation output screen showing:
    • Volume of raw acid needed
    • Volume of water needed
    • The equivalent acid concentration
    • The equivalent acid pH value
  12. Name of saved calculation or type in a name to save calculation under (??)
  13. Double tap the results window to copy results to clipboard
  14. Rotate pickerview to revert back to a saved calculation
  15. Swipe left on the pickerview to delete the selected record
  16. Double tap the pickerview to load the selected calculation. This is required when you recall the preferred units (step 3) and want to load back the saved caculation selected in the pickerview.

(?) Normality is similar in concept to molarity. Where molarity (M) represents the concentration of an ion or compound in solution, normality (N) represents the molar concentration only of the acid component (usually the H+ ion in an acid solution). Typically N = (M)(number of hydrogen or hydroxide ions).
