What are the major species present in the following mixtures of bases?
(b) 0.0010 M Ba(OH)2 and 0.070 M RbOH
OH -
H2O
RbOH
Ba(OH)2
Rb+
Ba2+
The major species present in the mixture of bases 0.0010 M Ba(OH)2 and 0.070 M RbOH are:
1. OH-: This is the common hydroxide ion present in both Ba(OH)2 and RbOH solutions.
2. H2O: Water is always present in aqueous solutions and does not undergo any significant reaction in this case.
3. RbOH: This is the compound RbOH itself, present in the RbOH solution.
4. Ba(OH)2: This is the compound Ba(OH)2 itself, present in the Ba(OH)2 solution.
5. Rb+: Since RbOH is a strong base, it completely dissociates in water to produce Rb+ ions.
6. Ba2+: Similarly, Ba(OH)2 is a strong base and completely dissociates in water to produce Ba2+ ions.
