Li + is easily leached in solution with its efficiency ,strongly, correlated with the ,acidic, strength (ie, displacement of Li + with H + to induce solubilization). However, cathode transition metals have low solubility as they exist in +3/+4 valence states in discharged cathodes and are difficult to leach due to the strong M–O bonds.

Water Research Center - pH of Drinking Water Water Balance

In general, a water with a pH < 7 is considered ,acidic, and with a pH > 7 is considered basic. The normal range for pH in surface water systems is 6.5 to 8.5 and for groundwater systems 6 to 8.5. Alkalinity is a measure of the capacity of the water to resists a change in pH that would tend to make the water more ,acidic,.
