In this case, the reaction is between sodium hydroxide (<strong>NaOH<\/strong>) and nickel(II) nitrate (<strong>Ni(NO\u2083)\u2082<\/strong>). First, let\u2019s write the <strong>balanced molecular equation<\/strong>:<\/p>\n\n\n\n<p><strong>Ni(NO\u2083)\u2082 (aq) + 2NaOH (aq) \u2192 Ni(OH)\u2082 (s) + 2NaNO\u2083 (aq)<\/strong><\/p>\n\n\n\n<p>This equation shows that nickel(II) hydroxide (<strong>Ni(OH)\u2082<\/strong>) forms as a <strong>precipitate<\/strong> (solid), while sodium nitrate (<strong>NaNO\u2083<\/strong>) remains dissolved in solution.<\/p>\n\n\n\n<p>To identify the <strong>spectator ions<\/strong>, we write the <strong>complete ionic equation<\/strong>:<\/p>\n\n\n\n<p><strong>Ni\u00b2\u207a (aq) + 2NO\u2083\u207b (aq) + 2Na\u207a (aq) + 2OH\u207b (aq) \u2192 Ni(OH)\u2082 (s) + 2Na\u207a (aq) + 2NO\u2083\u207b (aq)<\/strong><\/p>\n\n\n\n<p>Now, eliminate the ions that appear <strong>unchanged<\/strong> on both sides of the equation.
