Low-acid eating rebalances the diet: fewer high-acid foods and more high-alkaline ones. The pH scale runs from 0 to 14; distilled water has a pH of about 7 and is considered neutral, and acidity increases by 10 times with each decrease in a whole pH number.
Calcium: Physical Properties --silver-grey metal. melts at 840Â°C, boils at 1484Â°C to produce monatomic gas. density 1540 kg/m^3. Conductor of electricity but a poor one com â¦ pared to most other metals.Diamagnetic. Chemical properties -- tarnishes rapidly in air to produce a powdery, flaky oxide coating.Reacts steadily with water, giving off bubbles of hydrogen and a solution/slurry of alkaline, sparingly soluble calcium hydroxide. Flammable at high temperatures with oxygen, or air.an also burn in nitrogen to form calcium nitride or carbon dioxide to form calcium carbonate. Nearly all compounds are in oxidation state +2, and the water chemistry of calcium is dominated by the hydrated Ca(2+) ion.
gen atom. The chemical and physical properties of a substance refer to measurable or observable qualities or attributes that are used to distin-guish between different substances. Chemical properties describe how a substance interacts with other matter. Sodium and potassium, for example, react with water, but aluminum and gold do not. Physical properties are descriptive characteristics of matter. Examples of physical properties include color, density, conductivity, and malleability. Every substance will have a unique set of chemical and physical properties that can be used to identify it, because every type of substance has a unique atomic composition. It is often challenging to determine the identity of an unknown substance based on its chemical and physical properties.
