the difference of electronegativities of sodium and fluorine is 3.1 so they form ionic bonds . the metals and non metals usually have this difference higher than 1.7 and this and higher difference is always form an ionic bond between atoms

How many moles are in 4.5X1028 molecules of sodium fluoride NaF?

4,5.10e28 molecules of sodium fluoride NaF are equal to 0,745.10e5 moles.


What is the pH of 0.89 M NaF?

First recognize that NaF is the salt of a strong base (NaOH) and a weak acid (HF), so the pH will be alkaline. Next, look at the hydrolysis of NaF: NaF + H2O ---> NaOH + HF, or looking at it another way.... F^- + H2O ---> HF + OH- and here F^- acts as a base, so we need the Kb for NaF and that will be the inverse of the Ka for HF. The Ka for HF is 6.6x10^-4, so Kb = 1x10^-14/6.6x10^-4 = 1.5x10^-11. Now, Kb = [HF][OH-]/[F-] = (x)(x)/(0.89) = 1.5x10^-11 x^2 = 1.3x10^-11 x = 3.6x10^-6 = [OH-] pOH = -log 3.6x10^-6 = 5.44 pH = 8.6 (note the pH is alkaline, as expected)


Is NaF an inert solvent?

NaF can be said as inert because +1 and -1 valencies cancells each other................ so in that way we can say , it is Neutral........


What kind of bond is used in NaF?

Ionic bond is used in NaF. Sodium (Na) is a metal and fluorine (F) is a non-metal, so they form an ionic bond where electrons are transferred from sodium to fluorine.


Change hydrofluoric acid to a salt?

Hydrogen Fluoride can be changed to a salt by reacting it with a neutralizing agent such as Soda Ash (forming a sodium fluoride salt) or a caustic such as Potassium Hydroxide (to form potassium fluoride). Hydrogen Fluoride (HF) or hydrofluoric acid has unique properties that can present special handling hazards. It should only be handled by people with special training in the properties of HF and the first aid and medical procedures for exposure. Special protective clothing should be worn.

Is NaF and NaOH a buffer?

No, NaF and NaOH do not form a buffer solution together as a buffer solution requires a weak acid and its conjugate base, or a weak base and its conjugate acid. NaF is the salt of a weak acid (hydrofluoric acid) and a strong base (NaOH), so it does not act as a buffer. NaOH is a strong base and cannot act as a buffer solution by itself.


How many moles of NaF are in 34.2 grams of a 45.5 percent by mass NaF solution?

To determine the number of moles of NaF in 34.2 grams of a 45.5% by mass solution, first calculate the mass of NaF in the solution. Mass of NaF = 45.5% of 34.2 grams. Then convert the mass of NaF to moles using the molar mass of NaF. Finally, divide the mass of NaF by its molar mass to get the number of moles.


What is the conjugate acid of NaF?

The conjugate acid of NaF is HF (hydrofluoric acid). When NaF accepts a proton, it forms HF.
