Acidic
An acid is a molecule or ion capable of either donating a proton (i.e. hydrogen cation, H+), known as a Brønsted–Lowry acid, or forming a covalent bond with an electron pair, known as a Lewis acid. The first category of acids are the proton donors, or Brønsted–Lowry acids. In the special case of aqueous solutions, proton donors form the hydronium ion H3O+ and are known as Arrhenius acids. Brønsted and Lowry generalized the Arrhenius theory to include non-aqueous solvents. A Brønsted–Lowry or Arrhenius acid usually contains a hydrogen atom bonded to a chemical structure that is still energetically favorable after loss of H+. Aqueous Arrhenius acids have characteristic properties that provide a practical description of an acid. Acids form aqueous solutions with a sour taste, can turn blue litmus red, and react with bases and certain metals (like calcium) to form salts. The word ''acid'' is derived from the Latin , meaning 'sour'. An aqueous solution of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clanwilliam is situated at an elevation of , between the western slopes of the Cederberg mountains and the east bank of the Olifants River, which is impounded there by the Clanwilliam Dam. It lies just off the N7 national road, which runs from Cape Town to the Namibian border, and on the R364 road, which runs from Lamberts Bay to Calvinia. Clanwilliam is from Cape Town by road. The Dutch Reform Church has been a scheduled national monument since 1973.

Thee River
The word ''thou'' () is a second-person singular pronoun in English. It is now largely archaic, having been replaced in most contexts by the word ''you'', although it remains in use in parts of Northern England and in Scots (). ''Thou'' is the nominative form; the oblique/objective form is ''thee'' (functioning as both accusative and dative); the possessive is ''thy'' (adjective) or ''thine'' (as an adjective before a vowel or as a possessive pronoun); and the reflexive is ''thyself''. When ''thou'' is the grammatical subject of a finite verb in the indicative mood, the verb form typically ends in ''-(e)st'' (e.g., "thou goest", "thou do(e)st"), but in some cases just ''-t'' (e.g., "thou art"; "thou shalt"). Originally, ''thou'' (in , ) was simply the singular counterpart to the plural pronoun '' ye'', derived from an ancient Indo-European root. In Middle English, ''thou'' was sometimes represented with a scribal abbreviation that put a small "u" over the letter thorn: Ã ...
