WebAt 25 degrees Celsius, the aqueous solution of sodium chloride is neutral and has a pH of seven. The reason why the pH is equal to seven is because neither the cation nor the anion reacts with water, and water has a pH of … Web15 hours ago · Now, pH is calculated by taking the negative of the log of hydrogen ion concentration. Then this will gives us the pH as; pH = −log10 [H+ (aq)] pH = −log10 [10-7] = 7 Therefore, by the calculations, it is proved that the pH of sodium chloride when dissolved in water at room temperature i.e at 25°C, is equal to 7.

Solve the pH by substituting the given values. … WebThe pH of a salt solution is determined by the relative strength of its conjugated acid-base pair. Salts can be acidic, neutral, or basic. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride (NH4Cl). Salts that form from a weak acid and a strong base are basic salts, like sodium bicarbonate (NaHCO3). photo cd viewer
