Each instance of <a href="http://sw.opencyc.org/concept/Mx4rTr1cggxTQdeEUNw35C_xrg" class="cyc_term">IonicDecomposableCompoundType</a> is a type of compound whose instances decomposes under certain conditions in positively and negatively charged ions. <a href="http://sw.opencyc.org/concept/Mx4rTr1cggxTQdeEUNw35C_xrg" class="cyc_term">IonicDecomposableCompoundType</a> is a generalization of <a href="http://sw.opencyc.org/concept/Mx4rk-QXFOqPQdaTEP2JRDHw9A" class="cyc_term">IonicCompoundType</a> (those compounds of ions that form in three-dimensional blocks) and of compounds formed from a hydrogen ion [<a href="http://sw.opencyc.org/concept/Mx4r1dqAxv5tQdaHOfxtjDukgg" class="cyc_term">HydrogenPlusIon</a>] and an anion, including <a href="http://sw.opencyc.org/concept/Mx4rGKkOyvZLQdaONfI73-kRjQ" class="cyc_term">AcidType_Strong</a>. Note that strong acids can exist in molecular form (e.g., as gases) even though they dissolve into ions in aqueous solution. compound decomposable into ions IonicDecomposableCompoundType Pretty String (<a href="http://sw.opencyc.org/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> TERM STRING) means that STRING is the English word or expression (sequence of words) commonly used to refer to TERM. The predicate <a href="http://sw.opencyc.org/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> is used by the code which generates CycL to English paraphrases, but its applicability is not restricted to this use. prettyString WeakElectrolyte weak electrolyte The collection of all polyatomic chemical stuffs that partially decompose into ions when disolved in water.
