The salts you tested were held together by ionic bonds. The compounds were made of two types of ions, positive and negative, that were attracted to each other because of their opposite charges. Some ionic bonds take more energy to break. Based on your investigation, which compounds have bonds that require the most energy to break? A.
an ionic compound that completely dissolves in water, forming many ions

B.
an ionic compound that partially dissolves in water, forming some ions

C.
an ionic compound that does not dissolve in water, and thus does not form any ions
