NaOH is an example of an ionic crystal.
Option a
<h3><u>Explanation:</u></h3>Sodium Hydroxide is a "white solid ionic compound" consisting of sodium cations Na+ and hydroxide anions . If we look at the crystal structure of NaOH, we can see that it has the combinations of ionic and covalent bonds. The bond that is shared between Oxygen ( O ) and Hydrogen ( H ) is the covalent bond.
The Sodium ( Na ) is bonded with an "ionic bond to the hydroxide part of the compound". NaOH is an ionic solid because it is formed by the combinations of metal and non-metal. When the crystal of NaOH is dissolved in water it dissociates into Na+ ions (which is ionic in nature) and ions which bonds ionically to the other compounds.
