<u><em>Answer:</em></u>
It was a positive ion.
<u><em>Explanation</em></u>
In CaBr, ionic bond is present. When one of the atom loses electrons and gets positive charges and other atom gains electrons and become negative. As a result of positive and nagative charges , a ionic bond formed.
As in this case, Ca loses electrons and become positive ion while on the other hand bromide gets the electrons and become negative ion.
<em>Note:</em>
Electropositive atoms always loose electrons Like Ca while electronegative atoms always gain elelctrons like Br.
Explanation:
Species present are 
, 
and 
. Now, we will calculate the number of componenets present as follows.
C = n - E
where, E = number of independent equations
n = number of phases present
Therefore, we will calculate the number of components as follows.
C = 3 - 1
= 2
Since, sodium chloride (NaCl) will tend to form a homogeneous mixture in water. Therefore, phase will be equal to 1.
Therefore, it means that there are two components present in one phase.
