为什么CaO(aq)是Ionic oxide?
I"ll take a shot. If I made any mistake plz feel free to correct me, since I haven"t do Chemy for a while. I reckon you are trying to figure out the principle of naming compounds. Ca(HCO3)2 is Calcium Bicarbonate. It"s a compound, which has zero net charge. (aq)is standing for the aqueous solution, the net charge is not zero. Similarly, CaO is called Calcium Oxide n it is a compound as well. since CaO actually reacts with the water( the oxide become protonated to for a hydroxide ion). The CaO is an ionic oxide, or it"s not as stable as anions, it acts like sodium chloride. As your father told you, Calcium Oxide is a base. since after dissolving in the water, it realease the hydroxide (OH-) into the solution. You can take NaOH into account, which is a typical base. You are absolutely right about the Lithium Oxide(it"s an ionic compoud). However, there are some certain rules applied for naming those covalent compounds(non-metal), CO is called Carbon Monoxide, CO2 is called Carbon dioxide (The renown own) N2O5 is called Dinitrogen Pentoxide. You might feel a bit dizzy, it"s perfectly fine. 1:mono- 2:di- 3: tri- 4:tetra- 5:- penta-- 6:hexa- ...etc. Hopefully, I made myself understood n good luck with your chemmy Yep, since they are Molecular (Covalent) Compounds, they don"t follow the ionic rules. You are smart, lol. Seems you are in states or CA?
