The net ionic equation for the above reaction follows: Hence, the net ionic equation is written above. A solution is neutral when it contains equal concentrations of hydronium and hydroxide ions. For example, aspirin is an acid (acetylsalicylic acid), and antacids are bases. The cations will switch places in the products for double replacement reactions. OBJECTIVES Go establish the molarity press percent by grounds of acetic acid in grape. What is the relationship between the strength of an acid and the strength of the conjugate base derived from that acid? Derive an equation to relate the hydroxide ion concentration to the molarity of a solution of. According to Brnsted and Lowry, an acid (A substance with at least one hydrogen atom that can dissociate to form an anion and an \(H^+\) ion (a proton) in aqueous solution, thereby forming an acidic solution) is any substance that can donate a proton, and a base (a substance that produces one or more hydroxide ions (\(OH^-\) and a cation when dissolved in aqueous solution, thereby forming a basic solution) is any substance that can accept a proton. One of the most familiar and most heavily advertised applications of acidbase chemistry is antacids, which are bases that neutralize stomach acid. For dilute solutions such as those we are discussing, the activity and the concentration are approximately the same. Hint: neutralization reactions are a specialized type of double replacement reaction. Example \(\PageIndex{6}\): Predicting the outcome of a neutralization reaction. Thus water can act as either an acid or a base by donating a proton to a base or by accepting a proton from an acid. The BrnstedLowry definition of a base, however, is far more general because the hydroxide ion is just one of many substances that can accept a proton. 2013-03-24 23:02:54.
