The values of Kw as a function of temperature are as follows: Is the autoionization of water exothermic or endothermic? Choose the right variant. exothermic endothermic it depends on pressure it depends on temperature b What is the pH of pure water at 50°C? 6.631 From a plot of ln(Kw) versus 1/T (using the Kelvin scale), estimate Kw at 37°C, which is the normal physiological temperature.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
