NaF and K2CO3 will form basic solutions when dissolved in water. NaF does so because the fluoride ion is a weak base and reacts with water to form OH- ions. K2CO3 is a salt of a strong base (KOH) and a weak acid (H2CO3), and its solution is basic due to the hydrolysis of the carbonate ion, which also produces OH- ions.
