The key point to consider here is the nature of these ions in water.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Ba\u00b2\u207a (Barium ion)<\/strong>: The barium ion is a metal cation that does not hydrolyze (react with water) significantly to produce H\u207a or OH\u207b ions. Therefore, it does not affect the pH of the solution.<\/li>\n\n\n\n<li><strong>NO3\u207b (Nitrate ion)<\/strong>: Nitrate is the conjugate base of a strong acid (HNO3). Conjugate bases of strong acids are weak bases and do not undergo hydrolysis in water to any appreciable extent.
