What does HF mixed with NaF make?

When hydrogen fluoride (HF) is mixed with sodium fluoride (NaF), it forms a solution known as acidulated sodium fluoride, which is commonly used for topical fluoride treatments in dentistry to help prevent tooth decay.


What is chemical equation when a strong acid is added to a buffer solution containing NaF and HF?

When a strong acid is added to a buffer solution containing NaF and HF, the strong acid will react with the weak base (F-) to form HF. The buffer solution will resist changes in pH by the common ion effect, maintaining the solution's acidity around the initial pH of the buffer. The chemical equation can be written as H+ + F- ↔ HF.


The molar solubility of is not affected by the pH of the solution Na3PO4 NaF KNO3 AlCl3 or MnS?

That's correct. The molar solubility of Na3PO4, NaF, KNO3, AlCl3, and MnS is not affected by the pH of the solution because these compounds do not contain any acidic or basic groups that can significantly influence their solubility as pH changes. The solubility of these compounds is primarily determined by their intrinsic properties and the interactions between the ions in the compound.


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 salts is most basic in a .10 M solution NaF NaNO2 NaCH3COO NaOCl or NaCN?

In a .10 M solution, NaOH (sodium hydroxide) would be the most basic salt among the options listed. It dissociates in water to produce hydroxide ions (OH-) which makes the solution basic.

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.


How many grams of sodium fluoride are needed to prepare a 0.400m NaF solution that contains 750g of water?

To prepare a 0.400m NaF solution, you need to dissolve 0.400 moles of NaF per liter of solution. With 750g of water, you have about 0.416 L of water. To calculate the grams of NaF needed, multiply the molarity by the volume of solution in liters, then multiply by the molar mass of NaF (sodium fluoride: 41.99 g/mol). So, you would need about 6.991 grams of NaF.


What is the effect of adding NaF to a aqueous HF solution-a pH increases b h30 increases c hf increases?

c. The addition of NaF to an aqueous HF solution will increase the concentration of HF. This is because NaF will react with HF to form NaHF2, which increases the amount of HF present in the solution.


What does HF mixed with NaF make?

When hydrogen fluoride (HF) is mixed with sodium fluoride (NaF), it forms a solution known as acidulated sodium fluoride, which is commonly used for topical fluoride treatments in dentistry to help prevent tooth decay.


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.


Is NaF acidic basic or a salt?

It is BASIC because, if combined with water, it produces a strong base: NaOH


What is the mass percent of a sodium fluoride solution prepared by dissolving 0.64 moles of sodium fluoride into 63.5 grams of water?

To find the mass percent of sodium fluoride in the solution, we first need to calculate the total mass of the solution. The molar mass of sodium fluoride (NaF) is 41.99 g/mol. Mass percent = (mass of NaF / total mass of solution) x 100% Mass of NaF = 0.64 moles x 41.99 g/mol = 25.56 grams Total mass of solution = 25.56 g (NaF) + 63.5 g (water) = 89.06 g Mass percent = (25.56 g / 89.06 g) x 100% ≈ 28.7%


What is chemical equation when a strong acid is added to a buffer solution containing NaF and HF?

The buffer solution will resist changes in pH by the common ion effect, maintaining the solution's acidity around the initial pH of the buffer. The chemical equation can be written as H+ + F- ↔ HF.


Why is an aqueous solution of NaF basic?

NaF is a salt composed of sodium cation (Na+) and fluoride anion (F-). When NaF dissolves in water, it hydrolyzes to form NaOH and HF. The NaOH produced in this reaction is a strong base, resulting in the aqueous solution of NaF being basic.


Is naf a word?

Naf is not in the Oxford English dictionary.


What is the conjugate acid of NaF?

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