Strong bases and weak acids can hydrolyze into salts, raising the pH level over 7. Ammonium chloride (NH 4 Cl) is a salt whose solution has a pH of less than 7.
The pH will be less than seven when the solution is acidic and higher than seven when the solution is basic. Because Na2CO3 is a salt comprising a strong base and a weak acid, it will produce the highest pH in water. The pH scale determines how acidic or basic water is. The range is 0 to 14, with 7 representing neutrality. Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7. In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.
