Abstract

One of the ceramic clays known as RAJMAHAL clay was rendered into the H‐clay by leaching with 0.02 N HCl and washing it free from excess of the acid. The H‐clay was sieved through 120 mesh, and the clay suspension was shaken in a mechanical shaker for different intervals of time. It was observed that the p~H~ of the clay suspension took 8 hours to reach a constant p~H~ value.

The suspension was then titrated against 0.01 N NaOH solution both by conductometry and potentiometry. The points of equivalence obtained by both of these techniques were strikingly identical. There were three loops (two prominent and one suppressed) and three points of intersection in the potentiometric and conductometric curves respectively. These results have been discussed in the aspect of clay mineralogy.
