There are two types of ions in this compound, calcium ions and hydroxyl ions. The number of ions present in a sample can be calculated if the mass of the sample is known.
There are no ions in Ca(OH)2. Once placed in water, then there is 1 calcium ion (Ca^2+) and 2 hydroxide ions (OH^-).
Ca(OH)2

BaSO4 is insoluble in water so it is very weak electrolyte, ethanol can not produce ions so is non electrolyte other two are good electrolytes.
74.0932 g/mol
NaOH+CaCO3
Acid. It's actually a base (calcium hydroxide) sometimes called "slaked lime".
If a solution is basic it has how many ions
2 moles of Ca and 4 moles of OH
Nope... it is not.
Calcium Hydroxide, or CaOH2, is a base. Generally compounds containing hydroxyl groups and metals will act as bases in reaction.
In one mole of this solution, there are seven moles of H2O.
