The synthesis, ion exchange properties and analytical potentiality of niobium arsenate were investigated earlier. The present paper deals with the alkali and alkaline earth metal ion equilibrium studies at 30, ; 0 and 70^o. Some values for \(K^M_H\), \(\bigtriangleup\)G^o, \(\bigtriangleup\)H^o, \(\bigtriangleup\)S^o and \(\bigtriangleup\)\(S^-_{EX}\) have been calculated.
