Reaction with acids. Sodium hydroxide reacts with protic acids to produce water and the corresponding salts. For example, when sodium hydroxide reacts with hydrochloric acid, sodium chloride is formed: NaOH(aq) + HCl(aq) → NaCl(aq) + H 2 O(l) In general, such neutralization reactions are represented by one simple net ionic equation:
Apr 30, 2022 · The balanced molecular equation now involves a 1:2 ratio between acid and base. H2SO4(aq) + 2NaOH(aq) → Na2SO4 (aq) +H2O(l) H 2 SO 4 ( a q) + 2 NaOH ( a q) → Na 2 SO 4 ( a q) + H 2 O ( l) In order for the reaction to be a full neutralization, twice as many moles of NaOH NaOH must react with the H2SO4 H 2 SO 4.
( 1 CO 2 molecule × 2 O atoms CO 2 molecule) + ( 2 H 2 O molecules × 1 O atom H 2 O molecule) = 4 O atoms. The equation for the reaction between methane and oxygen to yield carbon dioxide and water is confirmed to be balanced per this approach, as shown here:
Apr 28, 2021 · Solution. The general reaction is as follows: H 2 SO 4 (aq) + KOH (aq) → H 2 O (l) + salt. Because the acid has two H + ions in its formula, we need two OH − ions to react with it, making two H 2 O molecules as product. The remaining ions, K + and SO 4 2−, make the salt potassium sulfate (K 2 SO 4 ). The balanced chemical reaction is as follows:
