There is no simple relationship. However, the Total Dissolved Solids (TDS) correlates with electrical conductivity and can affect pH,

Mohsen Golian

TDS correlates positively with

conductivity and affects pH. The higher the TDS, the higher the conductivity and the lower the pH, towards the

acidity.
