What types of compound can it (i) dissolve, and (ii) hydrolyse ? Water is called as universal solvent. Water is a good solvent due to its polarity. When an ionic or polar compound enters water, water molecules surround it. The relatively small size of water molecules typically allows many water molecules to surround one molecule of solute. The partially negative dipoles of the water are attracted to positively charged components of the solute, and vice versa for the positive dipoles. Therefore ionic compounds dissolve due to ion –dipole interaction.The covalent compounds like sugar , alcohol dissolve in water due to hydrogen bonding. Water can hydrolyse many metals and non-metallic oxides, hydrides etc.example. CaO +H2O→ Ca (OH) 2 ©TutorBreeze.com Please do not copy the answer given here Write to us for help in understanding the solution
