Calculate the content of your hydrochloric acid in g/L:
RS1=EP1*C01*C02/C00
End point*conc.(titrant)*molecular weight/sample size
To correct a formula, delete it with .
• Confirm the formula with .
• You may enter a text for the result output, see page
8.
• Enter the desired number of decimal places for the
result.
• Select the desired unit g/L with
a text as unit, see page 8.
The Titrino prompts for the calculation of the next result.
Quit the formula entry by pressing twice.
In order to be able to calculate the result, enter the calculation constants used in the for-
mula.

• Press .
The constants which have been used in the formula
are requested: input with digit keys, confirm with
.
C01: Concentration of your titrant= 0.1 mol/L.
Enter 0.1.
C02: Molar mass of HCl = 36.47 g/mol
Enter 36.47.
Now only the constant C00 is missing to perform the calculation. This constant is re-
served for the sample size. It can be entered directly.
