compare what happens when nacl and hcl are added to water. (hint: they will both dissolve but they will do so differently. pay close attention to the type of compounds they are.)

When NaCl is added to water, it dissolves into ions, Na+ and Cl-, since NaCl is a salt and a strong electrolyte. The resulting solution will have a neutral pH since NaCl is a neutral salt.
When HCl is added to water, it dissolved into ions as well, H+ and Cl-, since HCl is also a strong electrolyte. The resulting solution will have a pH of less than 7 since the H+ ions will increase the acidity of water.

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
