   Alkaline water is water that has a higher pH level than normal drinking water (between 7.5 and 9 for alkaline water versus 7 for normal drinking water). Alkaline water may come from springs or ...

3. Alkali - Wikipedia

   en.wikipedia.org/wiki/Alkali

   A basic salt of an alkali metal or alkaline earth metal [2] (this includes Mg(OH) 2 (magnesium hydroxide) but excludes NH 3 ). Any base that is soluble in water and forms hydroxide ions [3] [4] or the solution of a base in water. [5] (This includes both Mg(OH) 2 and NH 3, which forms NH 4 OH.) The second subset of bases is also called an ...

4. Alkalinity - Wikipedia

   en.wikipedia.org/wiki/Alkalinity

   This is the case since the amount of acid in the rainwater is low. If this alkaline groundwater later comes into contact with the atmosphere, it can lose CO 2, precipitate carbonate, and thereby become less alkaline again. When carbonate minerals, water, and the atmosphere are all in equilibrium, the reversible reaction CaCO 3 + 2 H + ⇌ Ca 2 ...

5. Are There Any Benefits to Drinking Alkaline Water? - AOL

   Alkaline water typically has a pH of 8 or 9, meaning it’s more basic than regular tap or bottled water, which can be neutral or slightly acidic depending on its source.

6. pH - Wikipedia

   en.wikipedia.org/wiki/PH

   In such cases, the system can be treated as a mixture of the acid or base and water, which is an amphoteric substance. By accounting for the self-ionization of water, the true pH of the solution can be calculated. For example, a 5×10 −8 M solution of HCl would have a pH of 6.89 when treated as a mixture of HCl and water. The self-ionization ...

7. Solubility chart - Wikipedia

   en.wikipedia.org/wiki/Solubility_chart

   The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
