Write the balanced molecular equation between phosphoric acid (H:PO4) and sodium hydroxide (NaOH).<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The balanced molecular equation for the reaction between phosphoric acid (H\u2083PO\u2084) and sodium hydroxide (NaOH) is:<\/p>\n\n\n\n

H\u2083PO\u2084 (aq) + 3 NaOH (aq) \u2192 Na\u2083PO\u2084 (aq) + 3 H\u2082O (l)<\/strong><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Phosphoric acid (H\u2083PO\u2084) is a triprotic acid, meaning it can donate three hydrogen ions (H\u207a) in a reaction. Sodium hydroxide (NaOH) is a strong base that dissociates completely in water to produce hydroxide ions (OH\u207b). In the reaction, the hydroxide ions from NaOH neutralize the hydrogen ions from H\u2083PO\u2084, resulting in the formation of water and a salt. The specific steps of the reaction are as follows:<\/p>\n\n\n\n

    \n
  1. Step 1: Ionization of Phosphoric Acid<\/strong>
    Phosphoric acid dissociates in water into hydrogen ions (H\u207a) and the phosphate ion (H\u2082PO\u2084\u207b), though it can release up to three protons in total. The initial dissociation is:
    [
    H\u2083PO\u2084 \\rightleftharpoons H\u207a + H\u2082PO\u2084\u207b
    ]<\/li>\n\n\n\n
  2. Step 2: Neutralization with Sodium Hydroxide<\/strong>
    Sodium hydroxide dissociates in water into sodium ions (Na\u207a) and hydroxide ions (OH\u207b). Each OH\u207b ion can neutralize one H\u207a ion. As phosphoric acid has three replaceable hydrogen ions, three OH\u207b ions will be required to fully neutralize the acid.<\/li>\n\n\n\n
  3. Step 3: Formation of Water and Salt<\/strong>
    Each hydrogen ion (H\u207a) reacts with a hydroxide ion (OH\u207b) to form water (H\u2082O). The phosphate ion (PO\u2084\u00b3\u207b) will combine with sodium ions (Na\u207a) to form sodium phosphate (Na\u2083PO\u2084), the salt produced in the reaction.<\/li>\n\n\n\n
  4. Step 4: Balanced Equation<\/strong>
    Since three hydroxide ions are required to neutralize all three hydrogen ions from phosphoric acid, the balanced equation is:
    [
    H\u2083PO\u2084 + 3 NaOH \u2192 Na\u2083PO\u2084 + 3 H\u2082O
    ]<\/li>\n<\/ol>\n\n\n\n

    This reaction is a typical example of an acid-base neutralization, where an acid (phosphoric acid) reacts with a base (sodium hydroxide) to produce a salt (sodium phosphate) and water.<\/p>\n","protected":false},"excerpt":{"rendered":"
