Can we Use fajans method to determined the exact concentation of a approximate 0.01 M hcl solution?

No. Fajans method relies on the naked eye, which is not as precise as analytical instruments.

Is Br2 aqueous or liquid?
Solid BeBr2 is covalent because although it is a metal non-metal compund the Be2+ ion is highly polarising due to its small size and the bonding is covalent. This is an exampe of Fajans rules. Its structure is like BeCl2, long chains with 4 coordinate Be.
When was Protactinium discovered?
The first isotope of protactinium (234mPa) was discovered by Kasimir Fajans and Otto Gohring in 1913. The isotope 231Pa of protactinium was discovered by Austrian/Swedish physicist Lise Meitner and by Otto Hahn, a German physical chemist in 1918 and simultaneously by Frederick Soddy and John Cranston. Who named it? The International Union of Pure and Applied Chemistry (IUPAC) often discusses the appropriate name for an element.
How many covalent bonds does boron form?
Beryllium generally forms covalent bonds. Beryllium is in the 2nd group and 2nd period so it is a very small cation. Smaller cation favors formation of covalent bonds. source(s):Fajan's Rule

When was Maksymilian Fajans born?
Maksymilian Fajans was born in 1827.

where was the element protactinium found?
Protactinium was discovered in 1913 by Fajans and Gohring in Karlsruhe, Germany.
Who discovered protactinium and what date did they discovered it?
Protactinium was discovered in 1913 by Fajans and Gohring in Karlsruhe, Germany.
Amongst LiF and LiI which has more covalent character and why?
LiI. Iodine is less electronegative. Li is very polarising and I- is more readily polarised (fajans rules)
What are the conditions of Fajans method in Precipitation Titration?
Fajans' method makes use of two facts regarding adorption effects on precipitates of a colloidal or semicolloidal state 1. finely divided precipitates tend to adsorb o their surface ions present in the solution. by doing so, the particles become electrically charged. 2. a preciptate tend to adsorb ions common to itself. thus, a precipitate of AgCl tend to adsorb Ag/Cl- in preference to forgeign ions like NO3 and Na. Futhermore, the adsorption indicator used should not be too weakly or too strongly adsorbed by the precipitate. Otherwise, false endpoints could be observed.
Does silver make ionic or covalent bonds?
Ionic. BUT because of Fajans rules silver salts have significant covalent character which expalins the low solubility of silver chloride.
Do LiCl contain covalent bonds?
No. But Li+ is small and polarising (Fajans rules apply)- so the salt is a little different in its behaviour from the other group 1 chlorides.
