Bredig arc’s method is not used for the preparation of sols of which of the following metal sols.

Bredig arc’s method is not used for the preparation of sols of which of the following metal sols. Correct Answer Vanadium

Bredig arc’s method, also known as electro – dispersion method is used for the preparation of metal sols of gold, silver and platinum. This method is not suitable when the condensation phase or the dispersion medium is an organic liquid since it causes considerable charring.

Arrange the following stages in a sequence, such that they result in an ogee curve between two parallel lines AB and CD, such that they are the tangents to the arc. m) Join the adjacent ends B and C with a straight line. n) Divide the line BC into four parts using the points P1, P2, P3. o) Draw lines such that they pass through the points P1, P2, P3, and are perpendicular to the line BC. p) Draw the perpendicular lines through the points B and C such that they cut the lines passing through P1, P3 respectively at E and F. q) With the center E draw an arc BP2 and with center F draw an arc P2C, thus arc BP2C is required ogee curve.
