How does the brønsted-Lowry theory define acids and bases?
Leviafan [203]

They define acids as proton donors, and bases as proton acceptors

If you were to have:

HNO3 + H2O -> H3O+. + NO3-

You can see that the nitric acid (HNO3) gave a hydrogen ion which has 1 proton, 0 neutrons and 0 electrons to the water so we just say that it gave a proton.

Now let's see a base

NH3 + H2O -> NH4+ + OH-

Now, you can see that the ammonia (NH3) gained a hydrogen ion (proton) from the water to become ammonium(NH4). which means it accepted a proton

That's basically it. Feel free to ask if you have any further questions

Suppose a solution was too concentrated for an accurate reading with the spectrophotometer. The concentrated solution was dilute
yan [13]
Using the law of <span>dilution:

</span>initial Molarity = 3.5x10⁻⁶ M

<span>Initial volume = 4.00 mL
</span>
final Molarity = ??

final volume = 1.00 mL

Therefore:

Mi x Vi = Mf x Vf

(3.5x10⁻⁶) x 4.00 = Mf x 1.00

1.4x10⁻⁵ = Mf x 1.00

Mf = 1.4x10⁻⁵ / 1.00 = 

 1.4x10⁻⁵ M
