Salts are typically made from the neutralization of acids and bases. The pH of the resulting solution depends on the strength of the acid and base from which the salt is derived.<\/p>\n\n\n\n<p><strong>1. Ba(NO\u2082)\u2082 \u2013 Barium Nitrite:<\/strong><\/p>\n\n\n\n<p>This salt dissociates in water into Ba\u00b2\u207a and NO\u2082\u207b ions. Barium (Ba\u00b2\u207a) is the cation from a strong base (Ba(OH)\u2082), and nitrite (NO\u2082\u207b) is the conjugate base of a weak acid (HNO\u2082 \u2013 nitrous acid). Since Ba\u00b2\u207a is a spectator ion and does not hydrolyze, and NO\u2082\u207b is the conjugate base of a weak acid, it hydrolyzes with water to form OH\u207b (hydroxide ions). This leads to a <strong>basic<\/strong> solution.<\/p>\n\n\n\n<p>The hydrolysis reaction is:<br>NO\u2082\u207b + H\u2082O \u21cc HNO\u2082 + OH\u207b<\/p>\n\n\n\n<p>The formation of OH\u207b raises the pH, making the solution basic.<\/p>\n\n\n\n<p><strong>2. K\u2082SO\u2083 \u2013 Potassium Sulfite:<\/strong><\/p>\n\n\n\n<p>This salt dissociates into 2 K\u207a and SO\u2083\u00b2\u207b ions. Potassium (K\u207a) comes from a strong base (KOH), so it is a spectator ion. Sulfite (SO\u2083\u00b2\u207b) is the conjugate base of a weak acid (H\u2082SO\u2083 \u2013 sulfurous acid). Like nitrite, sulfite undergoes hydrolysis and produces OH\u207b in the process.<\/p>\n\n\n\n<p>The hydrolysis reaction is:<br>SO\u2083\u00b2\u207b + H\u2082O \u21cc HSO\u2083\u207b + OH\u207b<\/p>\n\n\n\n<p>This reaction results in an increased concentration of hydroxide ions, making the solution <strong>basic<\/strong>.<\/p>\n\n\n\n<p><strong>Conclusion:<\/strong><\/p>\n\n\n\n<p>Both Ba(NO\u2082)\u2082 and K\u2082SO\u2083 form basic solutions in water because their anions (NO\u2082\u207b and SO\u2083\u00b2\u207b) are conjugate bases of weak acids and hydrolyze to produce hydroxide ions. Their cations are from strong bases and do not affect the pH.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Just have a simple question, is the aqueous solutions for the salts Ba(NO2)2 and K2SO3 acidic, basic, or neutral?
