Water is here base and acid both because hydogen ion acts as acid while hydoxide ions acts as base.

3. Vinegar (CH3COOH) is considered a weak acid because a. it releases a small percentage of hydrogen ions in water b. it contains an OH- function group c. it releases a small percentage of OH- in water it contains four hydrogen atoms 4. an acid is a substance that___ when added to water a. produces hydroxide atoms b. raises the pH of the solution c. produces hydrogen atoms d. produces hydronium ions 5. which of the following is an acid?...
Question 1 (1 point) The reaction of metal ions with dilute NaOH (Itd.OH") produces the same result as the reaction with dilute aqueous NH3 because they are both Arrhenius bases. True False Question 2 (1 point) Since dilute NaOH (Itd.OH") and dilute aqueous NH3 produce similar results, why do the results differ between excess NaOH (xs. OH") and concentrated aqueous NH3? The results differ because the ammonia (when added in excess amounts) can form an anionic complex with the metal...
Lab 5 Buffers 1. Dissolved ions in salt solutions can act as acids or bases and react with water to produce hydronium ions or hydroxide ions that contribute to the pH of the salt solution. Since strong acids and strong bases completely ionize in solution, the reverse reaction essentially does not occur, meaning that the resulting conjugate base of a strong acid or conjugate acid of a strong base do NOT act as acids or bases. Ions that are conjugate...
