which substances are bases? check all that apply. naoh koh h3bo3 nacl ca(oh)2 fe2o3
Answer
Brief Explanations:
Bases are substances that can accept protons (H⁺ ions) or release hydroxide (OH⁻) ions in solution. NaOH, KOH, and Ca(OH)₂ are strong bases as they dissociate to release OH⁻ ions. H₃BO₃ is an acid, NaCl is a salt, and Fe₂O₃ is a metal - oxide.
Answer:
NaOH, KOH, Ca(OH)₂
