  <dc:description>&lt;div class="hlFld-Abstract"&gt;&lt;div class="NLM_paragraph"&gt;A vacuum‐jacketed metal&lt;span&gt;&amp;nbsp;&lt;/span&gt;calorimeter&lt;span&gt;&amp;nbsp;&lt;/span&gt;for determining heats of solution in aqueous HF was constructed. The reaction vessel was made of&lt;span&gt;&amp;nbsp;&lt;/span&gt;copper&lt;span&gt;&amp;nbsp;&lt;/span&gt;and was heavily&lt;span&gt;&amp;nbsp;&lt;/span&gt;gold&lt;span&gt;&amp;nbsp;&lt;/span&gt;plated. The&lt;span&gt;&amp;nbsp;&lt;/span&gt;calorimeter&lt;span&gt;&amp;nbsp;&lt;/span&gt;has a cooling constant of 0.6 cal‐deg&lt;sup&gt;−1&lt;/sup&gt;‐min&lt;sup&gt;−1&lt;/sup&gt;, approximately ¼ that of the air‐jacketed&lt;span&gt;&amp;nbsp;&lt;/span&gt;calorimeters&lt;span&gt;&amp;nbsp;&lt;/span&gt;most commonly used with HF. It reaches equilibrium within 10 min after turning off the&lt;span&gt;&amp;nbsp;&lt;/span&gt;heater&lt;span&gt;&amp;nbsp;&lt;/span&gt;current. Measurements of the heat of solution of reagent grade KCl(−100 mesh dried 2 h at 200°C) at a mole ratio of 1 KCl to 200 H&lt;sub&gt;2&lt;/sub&gt;O gave Δ&lt;i&gt;H&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;= 4198±11 cal at 25°C.&lt;/div&gt;&lt;/div&gt;&lt;div class="article-paragraphs"&gt;&lt;div class="sectionInfo"&gt;&lt;h4 class="refHeading"&gt;&lt;a name="_i1" class="mce-item-anchor"&gt;&lt;/a&gt;&lt;/h4&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
