1.	The self ionization of water is endothermic. While increase the temp. than what is the effect on pH and value of K_w ?
Answer» Solution :`2H_2O_((l)) + "Heat" hArr H_3O_((aq))^(+)+OH_((aq))^(-)` Then increase the TEMPERATURE and according to Le-Chatelier.s principle the reaction will be forward and increase products and `K_w` increase. The VALUE of pH is LESS than 7. At higher temperature the pOH of water is high.
