Guida verificata passo dopo passo1
Understand that sodium hydroxide is a compound made of sodium (Na), oxygen (O), and hydrogen (H) atoms.
Recall that hydroxide is a polyatomic ion with the formula OH⁻, which consists of one oxygen and one hydrogen atom bonded together.
Since sodium (Na) typically forms a +1 cation and hydroxide (OH⁻) is a -1 anion, they combine in a 1:1 ratio to form a neutral compound.
Write the chemical formula by combining Na⁺ and OH⁻ ions, resulting in NaOH.
Verify that the formula NaOH represents one sodium atom, one oxygen atom, and one hydrogen atom, which matches the composition of sodium hydroxide.
