Table \(\PageIndex{1}\) lists the solubilities of some simple ionic compounds. Table salt (sodium chloride, or NaCl) is an ionic compound, meaning that the bond it forms results from the donation of an electron from one atom (here, Na) to another (Cl), rather than from the electron sharing seen in covalent bonds. The freezing point of camphor is 178.4 C and its molal freezing point, k is 40.0 C/m. 0000000016 00000 n Under most conditions, ionic compounds will dissociate nearly completely when dissolved, and so they are classified as strong electrolytes. ; Zeinstra, G.G. If thats not what you are looking for, but instead want to know what mass of KBr is present in this solution. Notice how the temperature dependence of \(\ce{NaCl}\) is fairly flat, meaning that an increase in temperature has relatively little effect on the solubility of \(\ce{NaCl}\). Moodley, T.; Singh, M. Current Stimuli-Responsive Mesoporous Silica Nanoparticles for Cancer Therapy. Your question is solved by a Subject Matter Expert.
