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.
It is the only way of dissolving CaCO3. HCl + CaCO3 --> Ca2+ + H2O + CO2 In neutral water CaCO3 is insoluble.
For example calcium carbonate (CaCO3).
CaCO3 is a base. It will neutralize acid and hence the pH of acid increases (tends to reach neutral pH)
I think you mean acetic acid. Eggshells contain calcium carbonate, CaCO3, which is a base.
Soda is acidic as it contains H2CO3 due to the dissolved CO2 within the soda. Chalk on the other hand is a basically CaCO3 which is a base CaCO3 + H2CO3 ---> CaCO3 + H20 + CO2 The reaction will continue until here is no more H2CO3 left i/e when the soda goes flat. If this occurs before or the carbonate (CO3) is reduce to CO2 then there will be a solid left in the soda in the form of CaCO3

Limestone, CaCO3, is reactive with naturally acidic rainwater which helps dissolve it.
CaCO3> Ca^2+ +CO3^2- Basic CaCOO3+H^+ > Ca2+ +HCO3^- Ph dissolution CaCO3+ 2H^+ > Ca2+ + H2O + CO2 acidic Ph dissolution CaCO3+ H2O +CO2 > Ca^2+ + 2HCO3^- CO2 reacts with the atmosphere

Limestones are mostly made up of Calcite or Calcium Carbonate (CaCO3). Calcium Carbonate is basic in nature.
Molar mass of CaCO3 = 66.1221g CaCO3/mole CaCO3. This means that 1 mole CaCO3 = 66.1221g CaCO3. To find the mass of 4.5 mole CaCO3, complete the following calculation: 4.5g CaCO3 X 1mol CaCO3/66.1221g CaCO3 = 0.068 mole CaCO3.
Calcium carbonate, CaCO3 is the ingredient of lime. CaCO3 is a base. If there is too much acid in the fields, by adding a base it can be neutralised - that way, the ground won't be too acidic or too basic and crops can grow in their ideal conditions.
Nothing, because calcium carbonate is insoluble in pure water but slightly acidic water as tap water may dissolve it slowly.
The pH of general rain water is approximately 5-6, slightly acidic. This is because the carbon dioxide in the air, reacts with the water droplets in the clouds, and forms carbonic acid: CO2 + H2O > H2CO3. This means, that because the rain is acidic, it can react with certain substances, such as marble (CaCO3 or NaCO3), and leave marks as it slightly dissolves. Also, to grow certain crops, the soil must either be neutral, or close to neutral. Some other plants though, the soil must be approximately 4-5 pH. Also, it is important in your blood. Blood should have a controlled pH of between 7.35, and 7.45. It must be carefully regulated, and if your blood is slightly alkaline or acidic, then there is medication you can take.
