Examples of monobasic in a Sentence
It is a monobasic acid forming salts which are permanent in air, but which are gradually oxidized in aqueous solution.
In addition to this, the further regularity has been observed that when the powerful monobasic acids are neutralized by the powerful monacid bases, the heat of neutralization is in all cases the same.
Teachers may wish to get technicians rather than students to add the monobasic sodium phosphate (NaH 2 PO 4) to the buffer.
In 1849 he discovered anhydrous nitric acid (nitrogen pentoxide), a substance interesting as the first obtained of the so-called " anhydrides " of the monobasic acids.
It is monobasic and yields salts which only crystallize with great difficulty; when liberated, from these salts by a mineral acid it forms a syrupy nonvolatile mass.
An acid is said to be monobasic, dibasic, tribasic, &c., according to the number of replaceable hydrogen atoms; thus HNO 3 is monobasic, sulphuric acid H 2 SO 4 dibasic, phosphoric acid H 3 PO 4 tribasic.
When oxidized this aldohexose is first converted into the monobasic galactonic acid, and then into dibasic mucic acid; the latter is optically inactive, so that its configuration must be one of those given in the sixth and seventh columns of the table.
When heated with monobasic saturated acids and zinc chloride it yields acridines.
This view, which was specially supported by Gay-Lussac and Leopold Gmelin and accepted by Berzelius, necessitated that all acids were monobasic. The untenability of this theory was proved by Thomas Graham's investigation of the phosphoric acids; for he then showed that the ortho- (ordinary), pyroand metaphosphoric acids contained respectively 3, 2 and I molecules of " basic water " (which were replaceable by metallic oxides) and one molecule of phosphoric oxide, P2 05.
Those derived from monobasic acids, obtained by the action of acid chlorides or anhydrides on urea, decompose on heating and do not form salts.
It behaves as a monobasic acid and forms unstable salts.
It is a monobasic acid, forming one normal and two acid potassium salts, and basic salts with iron, aluminium, lead and copper.
It is a very weak monobasic acid, and the aqueous solution has a very low electric conductivity.
Aliphatic monobasic acids are further divided according to the nature of the parent hydrocarbon.
Metaphosphoric acid, HP0 3, is a monobasic acid which may be regarded as derived from orthophosphoric acid by the abstraction of one molecule of water, thus H 3 PO 4 - H 2 O = HP0 3; its constitution is therefore (HO)P0 2.
Although the acid is monobasic, salts of polymeric forms exist of the types (MP0 3) n, where n may be 1, 2, 3, 4, 6.
