The molecular and net ionic … Witryna30 gru 2024 · NaCl is a neutral salt. It is made from the neutralization reaction of the strong acid, namely Hydrochloric acid (HCl) with a strong base, namely Sodium hydroxide (NaOH). The strong acid and a strong base will neutralize each other effects and a neutral solution forms. Hence, the pH value of the aqueous solution of NaCl is 7.
WitrynaWhat is the pH of NaF in water? The 0.895 M NaF solution has a pH of 8.55. What happens when NaF is dissolved in water? In water, NaF (s) will dissolve to produce Na+ (aq), the conjugate base of a strong acid, which will not react with water.However, F– will behave like a Brxf8nsted base, and accept a proton from water.This is called a … WitrynaSalts .

Witryna- [Instructor] Salts can form acidic solutions, neutral solutions, or basic solutions when dissolved in water. For example, if we dissolve sodium chloride in water, solid sodium chloride turns into sodium cations and chloride anions in solution. At 25 degrees Celsius, the aqueous solution of sodium chloride is neutral and has a pH of seven. WitrynaWhy and how NaF is strong base? Basic substance has a pH value above 7.Let us know about the strong basicity of NaF. NaF is basic because when dissolved in water the Na + ions of NaF combines with OH – ions of water to form NaOH. NaOH is a strong base because it can dissociate completely in water.NaOH can also be easily oxidised and …
