Lead(II) sulfide | PbS – PubChem.
What is PbS in chemistry?
Phosphate buffered saline (PBS) is a non-toxic solution used in many biological laboratories. Unlike water, PBS prevents cells rupturing or shrivelling up due to osmosis.
What type of compound is PbS?
Lead(II) sulfide | PbS – PubChem.
Why is PbS insoluble?
PbS shows a very low solubility in water, and it is insoluble in organic solvents . Any “dissolution” process in acids (hydrochloric acid, nitric acid, aqua regia) is accompanied with a chemical reaction whereby H2S is liberated and the corresponding soluble Pb2+ salts are formed.
How is PbS formed?
Following the creation of the Public Broadcasting Act (1967) , the government-funded Corporation for Public Broadcasting (CPB) was established, and in 1969 it founded the Public Broadcasting Service as a successor to NET. The PBS broadcast network debuted in 1970.

What is 1X PBS?
PBS, 1X liquid ( Phosphate buffered saline ) is a ready to use buffer solution commonly used in biological research. PBS buffer is ideal for maintaining a constant pH, and since it is isotonic and non-toxic to cells, it can be used in a wide variety of biological applications.
What does PBS contain?
Description. PBS (phosphate buffered saline) is a pH-adjusted blend of ultrapure-grade phosphate buffers and saline solutions which, when diluted to a 1X working concentration, contains 137 mM NaCl, 2.7 mM KCl, 8 mM Na 2 HPO 4 , and 2 mM KH 2 PO 4 .
What is Dulbecco’s PBS?
Description. Dulbecco’s phosphate-buffered saline (DPBS) is a balanced salt solution used for a variety of cell culture applications, such as washing cells before dissociation, transporting cells or tissue samples, diluting cells for counting, and preparing reagents.
Does PbS dissolve in NaOH?
PbS is insoluble in excess of NaOH .
Is the following compound soluble or insoluble in water PbS?
According to general solubility rules, PbS is not soluble in water .
Which compound is soluble in water PbS?
Lead sulfide (PbS) is an insoluble metal sulfide in water. It forms a black precipitate in the water. PbS dissolve in nitric acid .
What was the first PBS station?
KUHT-TV in Houston was the first public television station to go on the air, in 1952, and Alabama Public Television launched the first statewide public broadcasting network in 1955.
Who is PBS funded by?
PBS is a private, nonprofit media enterprise owned by its member public television stations.
