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.
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.
Yes, an aqueous solution of NaHCO3 (sodium bicarbonate) is slightly basic.
It is BASIC because, if combined with water, it produces a strong base: NaOH
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.
Lithium chloride aqueous solution is neutral. It will not significantly alter the pH of the solution.

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.
basic in nature
Aqueous solution of borax is basic in nature and will turn red litmus paper blue. This is because borax can accept protons from water, making the solution basic.
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.
It is a neutral salt but its aqueous solution is acidic in nature.
