I will dissolve in water to form Na+ and F-
NaF <-> Na+ + F- (
NaF is not particularly soluble at room temperature so it might need some heating.
After this step the F- anion will react with an H2O molecule to create an HF molecule.
F- + H2O <-> FH + OH-
Note that F- like other halogens is not likely to attack an hydrogen molecule, however what make F- unique is that the bond it creates is so strong that once it is made, it is very difficult to break. As a result the FH form will exist in solution and accumulate up to a certain amount(the bond can still be broken however, so it is not a strong base), hence why F- is a weak base unlike other halogen ions which are neutral.

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.

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.
Is NaF acidic basic or a salt?
NaF is a salt, specifically an ionic compound formed from a metal (sodium) and a non-metal (fluorine). In solution, NaF dissociates into Na+ and F- ions.
Does the litmus paper test determine if an aqueous solution is basic?
Yes, the litmus paper test can determine if an aqueous solution is basic. If the litmus paper turns blue, it indicates that the solution is basic. If it remains red, the solution is acidic.
Is ZnSO4 acidic or basic?
ZnSO4 is neutral in aqueous solution because it does not exhibit acidic or basic properties.
Is Lithium chloride aqueous solution acidic or basic?
Lithium chloride aqueous solution is neutral. It will not significantly alter the pH of the solution.

Is an aqueous solution Lic2h3o3 acidic basic or neutral?
An aqueous solution of LiC2H3O2 is slightly basic. This is because the acetate ion (C2H3O2−) is the conjugate base of acetic acid, which is a weak acid. The presence of this ion makes the solution slightly basic.
An aqueous solution contain 0.10M NaOH means the solution is?
Basic as NaOH is a strong base.
What is the action of an aqueous solution of borax on litmus?
An aqueous solution of borax will have a slightly basic pH. Litmus is a pH indicator that turns blue in basic solutions and red in acidic solutions. Therefore, when litmus is added to an aqueous solution of borax, it will likely turn blue.
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 action of litmus with aqueous solution Na2CO3?
Red litmus paper turn blue in basic solutions; sodium carbonate solution is basic.
