temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.
is the process of separating the components or substances from a liquid mixture based on the boiling point of every component.
is defined as the ratio between mass and volume or mass per unit volume. It is a measure of how much stuff an object has in a unit volume (cubic meter or cubic centimeter). Unit: g/mL or kg/m3

TSS is the dry-weight of suspended particles, that are not dissolved, in a sample of water that can be trapped by a filter that is analyzed gravimetrically using a filtration apparatus.
TSS is the dry-weight of suspended particles, that are not dissolved, in a sample of water that can be trapped by a filter that is analyzed gravimetrically using a filtration apparatus.
is a collection of quantitative or numerical data that describes a property of an object or event.
Is a method of separating and analyzing compounds that can be vaporized without decomposition.
Is a method of separating and analyzing based on the characteristic interaction between sample’s ions, mobile phase and stationary phase.
The Bunsen reaction is a chemical reaction that describes water, sulfur dioxide, and iodine reacting to form sulfuric acid and hydrogen iodide: 2H2O + SO2 + I2 → H2SO4 + 2HI
The Bunsen reaction optimum pH of 5-8
To absorb CO2 that is produced from bacteria.
True. It is usually 2-4 times depends on the water itself.
pKa of these acids in decreasing order is HNO3>HCl>H2SO4,which means the H2SO4 is the strongest acid.
1% is equal to 10000 ppm
API gravity, is a measure of how heavy or light a petroleum liquid is compared to water.
is the process where solvent molecules move through a semipermeable membrane from a dilute solution into a more concentrated solution (which becomes more dilute).
Density is defined as the ratio between mass and volume or mass per unit volume. It is a measure of how much stuff an object has in a unit volume (cubic meter or cubic centimeter). Unit: g/mL or kg/m3
a process in which a chemical mixture carried by a liquid or gas is separated into components as a result of differential distribution of the solutes as they flow around or over a stationary liquid or solid phase.
A plasma is a hot ionized gas consisting of approximately equal numbers of positively charged ions and negatively charged electrons.
is a gas that has been turned into a liquid by cooling or compressing it.
is an indicative measure of the amount of oxygen that can be consumed by chemical reactions in a measured solution.
is the amount of dissolved oxygen needed (i.e. demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period.
is the amount of carbon found in an organic compound.
are organic chemicals that have a high vapor pressure at ordinary room temperature.
is the ratio of the density of a substance to the density of water.
bromine number—the number of grams of bromine that will react with 100 g of the specimen under the conditions of the test. Bromine index is bromine number divided by 1000.
ASTM D1159 for 95-165 Br. NoASTM D2710 for les than 0.5 Br. No
Definition: is a measure of hydrogen ion concentration, a measure of the acidity or alkalinity of a solution. (Without unit). Principle: measuring hydrogen concentration by separating it from solution using membrane electrode.
Definition: is a measure of water’s capability to pass electrical flow (Unit: µS/cm). Principle: measuring electron flow using Wheatstone bridge circuit with platinum electrode in each stream.
TSS is the dry-weight of suspended particles, that are not dissolved, in a sample of water that can be trapped by a filter that is analyzed gravimetrically using a filtration apparatus.
Definition: is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized or micro-granular (colloidal sol) suspended form. Principle: gravimetric method by Filtering the sample using 0.45 µm filter and evaporating up the filtrate solution in 105°C.
is the lowest temperature at which vapors of the material will ignite, when given an ignition source.
