Total dissolved solids ( TDS) 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. TDS are often measured in parts per million (ppm). TDS in water can be measured using a digital meter.
Conductivity (electrolytic) Conductivity or specific conductance of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is siemens per meter (S/m). Conductivity measurements are used routinely in many industrial and environmental applications as a fast, inexpensive and reliable way of ...
Sodium tetradecyl sulfate. CCCCC (CC)CCC (CC (C)C)OS (=O) (=O) [O-]. [Na+] Sodium tetradecyl sulfate ( STS) is a common anionic surfactant. The compound consists of the sodium salt of the micelle -forming sulfate ester of tetradecanol. It is a white, water-soluble solid of low toxicity with many practical uses. [1]
Total suspended solids. Total suspended solids ( 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 using a filtration apparatus known as sintered glass crucible. TSS is a water quality parameter used to assess the quality of a specimen of any type of ...
Tetraethyl orthosilicate, formally named tetraethoxysilane ( TEOS ), ethyl silicate is the organic chemical compound with the formula Si (OC 2 H 5) 4. TEOS is a colorless liquid. It degrades in water. TEOS is the ethyl ester of orthosilicic acid, Si (OH) 4. It is the most prevalent alkoxide of silicon.
Triethylenetetramine ( TETA and trien ), also known as trientine ( INN) when used medically, is an organic compound with the formula [CH 2 NHCH 2 CH 2 NH 2] 2. The pure freebase is a colorless oily liquid, but, like many amines, older samples assume a yellowish color due to impurities resulting from air-oxidation. It is soluble in polar solvents.
The law was actually the last of the laws to be formulated. First law of thermodynamics. d U = δ Q − δ W {\displaystyle dU=\delta Q-\delta W} where. d U {\displaystyle dU} is the infinitesimal increase in internal energy of the system, δ Q {\displaystyle \delta Q} is the infinitesimal heat flow into the system, and.
Trimethylolpropane (TMP) is the organic compound with the formula CH 3 CH 2 C (CH 2 OH) 3. This colourless to white solid with a faint odor is a triol. Containing three hydroxy functional groups, TMP is a widely used building block in the polymer industry.
