- The reaction between sodium (Na) and water (H 2 O) forms sodium hydroxide (NaOH) and hydrogen gas (H 2). Here is the balanced equation for the reaction, written two ways: 2 Na (s) + 2 H 2 O → 2 NaOH (aq) + H 2 (g) 2 Na (s) + 2 H 2 O (l) → 2 Na + (aq) + 2 OH – (aq) + H 2 (g)

Jun 22, 2011 · When sodium hydroxide is dissolved in water it feels warm, which indicates an exothermic reaction. NaOH (s) → Na + (aq) + OH – (aq) TOPICS COVERED: – exothermic reactions. – dissolution. – solubility. MATERIALS NEEDED: – 125mL Erlenmeyer flask w/ 30mL of water. – 3g NaOH. PROCEDURE: 1. Add NaOHto the flask. 2. Swirl to dissolve.
Jul 22, 2022 · We have written this equation using a single arrow because sodium hydroxide is a strong base and is essentially 100% ionized in solution. The hydroxide anion (\(\ce{OH^{–}}\)) reacts with the hydronium ion (\(\ce{H3O^{+}}\)) to form two moles of water, as shown in the equation given below.
Sodium hydroxide is also produced by combining pure sodium metal with water. The byproducts are hydrogen gas and heat, often resulting in a flame. 2 Na(s) + 2 H 2 O(l) → 2 NaOH(aq) + H 2 (g)
Apr 28, 2021 · Answer. Neutralization reactions and net ionic equations. In CHE 103, we examined how ionic compounds dissociate in water. In this chapter, we also learned that acids can also undergo dissociation in water. Thus, sodium hydroxide, NaOH, is dissolved in water, it ionizes to form the sodium cation and the hydroxide anion (HO – ).
May 9, 2021 · Sodium hydroxide is a strong base that dissociates completely into its ions in water, raising the pH of the liquid. The reaction between the metal and water is exciting, but adding a pH indicator to the water improves interest because the water changes color as the metal reacts.
