pH value(not the 'unit' just the scale)
pH is not a measure of how strong an acid is. pH is a measure of the concentration of hydronium ions in a solution, which is dependent on both the strength of the acid or base and its concentration in a given solution.
The pH of something (measure of acid or base) is determined by the concentration of hydrogen molecuels. acids have more while bases have less
The concentration of dissociable H+ ions is a measure of the acidity of the substance. The concentration of dissociable OH- ions is a measure of the basicity of the substance.
The burette can be filled with either acid or base. The acid will go into the burette only if you want to titrate a base , i.e. you don't know the concentration of the base and want to find out. The solution of known concentration goes always into the burette (in order to be able to measure the volume taken to complete the reaction) and so if you wanted to find out the concentration of an acid you would put the base into the burette.
The concentration of an acid or base in solution is measured in moles per litre. The strength of an acid or base in solution is measured on the pH scale. This is the negative log of the hydrogen ion concentration. It's a pure number, there are no units.

False
yes, the oxalic acid would be the standard acid by which the base is titrated and the concentration determined. if the oxalic acid is 'around' 1M, that could mean anything
Determination of the concentration of a base by titration with acids or determination of the concentration of an acid by titration with bases. (http://en.wikipedia.org/wiki/Acid-base_titration)
Usually a strong acid will produce a lower pH, but not always. pH is not a measure of the strength of an acid (or base) but the acidity of a solution, which is dependent on both the strength of the acid or base and its concentration in the solution.
The negative logarithm of the hydrogen ion concentration, [H+], a measure of the degree to which a solution is acidic or alkaline. An acid is a substance that can give up a hydrogen ion (H+); a base is a substance that can accept H+. The more acidic a solution the greater the hydrogen ion concentration and the lower the pH; a pH of 7.0 indicates neutrality, a pH of less than 7 indicates acidity, and a pH of more than 7 indicates alkalinity. The pH is used as a measure of whether the body is maintaining a normal acid-base balance.
There is no definite pH of hydrochloric acid or any other substance. pH is a measure of the concentration of hydrogen ions in a solution which depends on both how strong an acid or base is and how concentrated it is (how much is dissolved in a given volume of water). Because hydrochloric acid is a strong acid the pH can be calculated as the negative logarithm (base 10) of its molar concentration up to a pH of 7.
