No, CaCO3 is not a strong base. It is a weak base, known as calcium carbonate. When dissolved in water, it only partially ionizes to release hydroxide ions.
No, calcium carbonate is a base (an alkali.)
It is a Chemical Salt. Chemical Salts have a metal cation , Calcium in this case, and an acidic anion, carbonate in this case. Ca^(2+) + CO3^(2-) = CaCO3 Most carbonates are INSOLUBLE to water, but will react with acids/
No, CH3O is not a strong base. It is a weak base.
No, ETOH (ethanol) is not a strong base. It is a weak base.
Personally, I use this method to determine if an ionic solid is acidic/basic/neutral. Let's take a look at the ions in this compound: Ca2+ and CO32- . Ca2+ is found in Ca(OH)2 , which is a very strong base. CO32- is found in H2CO3 , which is a weak acid. So, one ion comes from a strong base, while another comes from a weak acid. Overall, this compound must be basic. There are also other methods. You can add an acid to the solid. There is a reaction, so the solid must be basic. If you add a base, it doesn't react.

# The shells aren't made of calcium, they're made of calcium carbonate. # Calcium carbonate is the salt of a strong base and a weak acid, and is therefore weakly alkaline. I understand that you can make CaCO3 by the following process: HCO3 + CaOH => CaCO3 +H2O But once you have made CaCO3 ( a slightly alkaline salt) from the acid and base, what is happening to the CaCO3 in the H2O that is making the water more basic? In other words, how can CaCO3 have anything to do with the lone OH- ions present in the water?
CaCO3 (calcium carbonate) is a mild base, and as such reacts to neutralise acids. Vinegar is a dilute solution of acetic acid (AcH). CaCO3 + 2AcH --> H2O + CO2 + CaAc

A salt is formed when a strong acid reacts with a strong base.
Potassium hydroxide (KOH) is a strong base. It dissociates completely into ions in water, making it a strong electrolyte and a good conductor of electricity.
