In finance, the quick ratio, also known as the acid-test ratio is a type of liquidity ratio, which measures the ability of a company to use its near-cash or 'quick' assets to extinguish or retire its current liabilities immediately. It is defined as the ratio between quickly available or liquid assets and current liabilities.
The acid number is a measure of the number of carboxylic acid groups ( −C (=O)OH) in a chemical compound, such as a fatty acid, or in a mixture of compounds. [ 2] In other words, it is a measure of free fatty acids (FFAs) present in a substance. In a typical procedure, a known amount of sample dissolved in an organic solvent (often ...
Saponification value or saponification number ( SV or SN) represents the number of milligrams of potassium hydroxide (KOH) or sodium hydroxide (NaOH) required to saponify one gram of fat under the conditions specified. [1] [2] [3] It is a measure of the average molecular weight (or chain length) of all the fatty acids present in the sample in ...
Para-aminohippurate (PAH) clearance is a method used in renal physiology to measure renal plasma flow, which is a measure of renal function. [citation needed]PAH is completely removed from blood that passes through the kidneys (PAH undergoes both glomerular filtration and tubular secretion), and therefore the rate at which the kidneys can clear PAH from the blood reflects total renal plasma flow.
An acid–base titration is a method of quantitative analysis for determining the concentration of Brønsted-Lowry acid or base (titrate) by neutralizing it using a solution of known concentration (titrant). [ 1] A pH indicator is used to monitor the progress of the acid–base reaction and a titration curve can be constructed.
Delta ratio. In nephrology, the delta ratio, or " delta-delta " (denoted Δ/Δ ), is a formula that can be used to evaluate whether a mixed acid–base disorder ( metabolic acidosis) is present, and if so, assess its severity. The anion gap (AG) without potassium is calculated first and if a metabolic acidosis is present, results in either a ...
Calculation. The anion gap is a calculated measure. It is computed with a formula that uses the results of several individual lab tests, each of which measures the concentration of a specific anion or cation. The concentrations are expressed in units of milliequivalents / liter (mEq/L) or in millimoles/litre (mmol/L).
Acid test. An acid test is a qualitative chemical or metallurgical assay utilizing acid. Historically, it often involved the use of a robust acid to distinguish gold from base metals. Figuratively, the term represents any definitive test for attributes, such as gauging a person's character or evaluating a product's performance.
