Unformatted text preview: color of phenolphthalein Change color of phenolphthalein pink Reacts with active metals to produce hydrogen gas Have a slippery, soapy feeling React with carbonates to produce CO2 React with bases React with acids 1 Chemistry 52 EXPERIMENT #2 When acids and bases react with one another in equal proportions, the result is a neutralization reaction, which produces neutral products: salt and water. Neutral means in this context, that these products do not change the color of litmus or phenophtalein, do not have a sour or bitter taste, therefore they are “neither acidic nor basic”. The following equations represent two typical acidbase neutralization reactions: Neutralization HCl(aq) + NaOH(aq) ──────────────> NaCl(aq) + H2O(l) Acid Base Salt water Neutralization H2SO4(aq) + 2 KOH(aq) ─────────────> K2SO4(aq) + 2 H2O(l) Acid Base Salt water +
Note that a salt is any compound of a cation (other than H ) with an anion (other than 2
OH or O ─ ). The word salt in everyday conversati...
