We are asked to calculate the pH of 0.261 M RbOH.
Bases are characterized by THREE major features: they may possess metals, they may have a negative charge or they may be an amine.
Any Group 1A metal when combined with OH –, H –, O2– or NH2 – makes a STRONG BASE.
Strong Bases are strong electrolytes that completely dissociate into ions when dissolved in water.
Rb is a group 1A metal so RbOH is a strong base.
What is the pH of a 0.261 M solution of RbOH? Enter your answer with two decimal places.
