Rudolph Wegscheider

Formula:

Na₅H₃(CO₃)₄

Colour:

Colourless

Lustre:

Vitreous

Hardness:

2½ - 3

Specific Gravity:

2.341

Crystal System:

Triclinic

Name:

Named by Joseph J. Fahey, K.P Yorks, and Daniel E. Appleman in 1961 in honor of Rudolf Wegscheider (8 October 1859, Großbetschkerek, Austrian Empire - 8 January 1935, Vienna, Austria), chemist. In 1913, he first produced the synthetic compound.
