Explain why you get a basic solution when you dissolve NaF in water.

SashulF [63]

Answer:

That's because in water NaF will dissolve to produce Na+,the conjugate base of a strong acid which will not react with water.however F- will behave like a bronsted base, and accept a proton from water.this is called hydrolysis reaction, because a molecule of water is broken up.

a conjugate base is what I leftover after an acid loses a hydrogen ion.

I hope this helps

If a student mixes 75 mL of 1.30 M HNO3 and 150 mL of 6.5 M NaOH. is the final solution acidic, basic, or neutral

raketka [301]

Answer:

The solution is basic.

Explanation:

We can determine the nature of the solution via determining which has the large no. of millimoles (acid or base):

If no. of millimoles of acid > that of base; the solution is acidic.

If no. of millimoles of acid = that of base; the solution is neutral.

If no. of millimoles of acid < that of base; the solution is basic.

We need to calculate the no. of millimoles of acid and base:

no. of millimoles of acid (HNO₃) = MV = (1.3 M)(75.0 mL) = 97.5 mmol.

no. of millimoles of base (NaOH) = MV = (6.5 M)(150.0 mL) = 975.0 mmol.

∴ The no. of millimoles of base (NaOH) is larger by 10 times than the acid (HNO₃).

So, the solution is: basic.
