Acid Strength - Texas Instruments
The graph of pH vs Molar concentration is logarithmic. The analysis on my calculator gave me the following relation: Y = 2.5486 + (-0.2337 ln X) where Y is pH and X is Molarity. This means that the pH decreases as the concentration of the acid increases. This relation has a limited application as maximum acid concentration is 12 to 14 M

After the calibration graph is complete, you will react a known mass of a sample of bronze with nitric acid. Copper(II) ions will be produced in the resulting solution. The solution’s absorbance will be measured, and its concentration will be read from the graph. Finally you will be able to calculate the percent copper in the original brass ...

Enter: 11.612 ( +/- ( 2nd ( log The calculator answer should be 2.443430553 x 10-12. The original pH had 3 SD’s, so the answer must also have 3 SD’s (Remember the answer is NOT a pH, so digits to the LEFT of the decimal point are also significant!) . Remember that concentration also has a unit!. So the answer would be reported as:
