<br/><br/> Calorimetric measurements of the heat of solution of nitronium perchlorate (NO(2)ClO(4)) and of a mixture of potassium nitrate and potassium perchlorate in aqueous potassium hydroxide have been made. These are combined to give: [Formula: see text] from which the standard heat of formation of nitronium perchlorate is calculated as [Formula: see text] in which the uncertainty represents twice the estimated overall standard deviation of the result.
