Solubility in 5% NaHCO3 (aq) and 5% NaOH(Aq)
Compounds that dissolve in sodium bicarbonate (Why?), a weak base,are relatively strong acids. Compounds that dissolve in NaOH(Why?), a strong base, may be either strong or weak acids. Thus,once can distinguish weak and strong acids by determing theirsolubility in both strong and weak bases. Some examples of strongeracids that are soluble in both NaOH and NaHCO3 are: Carboxylicacids (why stronger?), o/p-substituted di and trinitrophenols (whystronger?)

Why do ionic compounds dissolve well in water? Select all that are true.
Question 5 options:
Because water and ionic compounds are both polar | ||||||||||||||||||||||||||||||||||||||||||||
Water molecules have partial charges that attract the ions in the solid compound, causing it to dissociate into separated ions | ||||||||||||||||||||||||||||||||||||||||||||
Because organic compounds are nonpolar | ||||||||||||||||||||||||||||||||||||||||||||
Water molecules can surround an ion, and neutralize the ion's charge using either it's partial positive or negative side. | ||||||||||||||||||||||||||||||||||||||||||||
The individual ions are solvated by water molecules which stabilizes the ions 2. Which compound is soluble in ether but not soluble in aqueous sodium hydroxide? Question 2 options:
