A beer bottle is a bottle made to contain beer, usually made of glass and comes in various sizes, shapes, and colors (usually brown or green). Dark amber or brown glass greatly reduces the presence of UV light, a contributing factor of beer spoilage. However, lighter-colored bottles are often used for marketing reasons.
Water’s composition (two parts hydrogen to one part oxygen) was discovered by the London scientist Henry Cavendish (1731-1810) in about 1781. He reported his findings in terms of phlogiston (later the gas he made was proven to be hydrogen) and dephlogisticated air (later this was proven to be oxygen).
A neutralization reaction is the reaction between an acid and a base to produce water and a salt. A salt is another name for an ionic compound and the specific salt produced depends on the acid and base involved. The product solution is neutral while the starting solutions are acidic and basic respectively.
