In nutrition, certain foods have an acidic effect on the body after consumption, and certain foods have an alkaline effect. Plant foods, such as ginger, are the most alkaline-promoting foods. Ginger has a pH of 5.6 to 5.9, similar to that of figs, fennel, leeks, parsnips and romaine lettuce.
The reaction between aluminum and bromine is very exothermic (DH o = -1022 kJ). This drives the entire process, and energy is given off in the form of light and heat: 2 Al (s) + 3 Br 2 (l) --> 2 AlBr 3 (s) The product of this reaction is a molecular solid with the formula Al 2 Br 6, but the formula is often written as AlBr 3.
Bromine has a low pH of around 4, and using bromine tablets will slowly lower pH and alkalinity over time, requiring additions of a base chemical to raise pH and alkalinity. The same can be said for chlorine tablets, which have a pH even lower, around 3. Bromine is far less affected by pool or spa water pH than chlorine, and able to be an active sanitizer at high ph levels of 7.8 â 8.2.
