# Sulfur Calculator

SO2 is a chemical substance called Sulphur Di-Oxide used in the reduction of oxidation reactions and microbial activity in wine. Here is the online sulfur calculator to calculate the molecular SO2 present in the wine. Just enter the quantity of free SO2 and pH of wine in this molecular SO2 in wine calculator to get the quantity in ppm or mg/L units. This tool will be a useful one for the winemakers to calculate the molecular sulfur within the fractions of seconds.

## Molecular SO2 in Wine Calculator

SO2 is a chemical substance called Sulphur Di-Oxide used in the reduction of oxidation reactions and microbial activity in wine. Here is the online sulfur calculator to calculate the molecular SO2 present in the wine. Just enter the quantity of free SO2 and pH of wine in this molecular SO2 in wine calculator to get the quantity in ppm or mg/L units. This tool will be a useful one for the winemakers to calculate the molecular sulfur within the fractions of seconds.

#### Formula:

r = a / [1 + 10(p - 1.8)] Where, a = Free SO2 r = Molecular SO2 p = pH of the Wine

### Example:

Calculate the molecular SO2 in wine which has the free SO2 of 50 ppm, and pH of 5.

#### Solution:

r = 50 / [1 + 10(5 - 1.8)]
= 0.0315 ppm.
