Answer: 10^3

Explanation:-

pH is the measure of acidity or alkalinity. It is also defined as negative logarithm of hydrogen ion concentration.

pH=-log[H_3O^+]

Given: pH = 3

Thus 3=-log[H_3O^+]

[H_1^+]=10^{-3}

6=-log[H_3O^+]

[H_3O^+]=10^{-6}

\frac{10^{-3}}{10^{-6}}=10^3

Thus H_3O^+ changes by 10^3 units.

(a) What is the charge density of an ion, and what two properties of an ion affect it?
olga nikolaevna [1]

Charge density is the ratio of the charge of ions to the volume of ions.

<h3> Factor affecting charge density</h3>

It depends on the following properties of ion as

  • Charge on the ion.
  • Volume of the ions.

The lithium ion, Li⁺, has half of the radius of the potassium ion, K⁺. That is why, Li⁺ have a electric field 4 times stronger than the electric field of K⁺ and thus it have 4 times stronger force of attraction.

All the ions: Li⁺, Na⁺, K⁺, Rb⁺, Cs⁺, have the similar electric charge +1.6×10⁻¹⁹ C. As we know that, volume is directly proportional to the third power of their radius. Therefore, smaller ions have less charge density than bigger one.

We can say that charge density decreases down across period due to decrease in the radius which further reduces the volume of ions.

Charge density increases along group due to increase in the radius which further increases the volume of ions.

Thus, we can say that charge density depends on the charge and volume of the ions.

g chemist accidentally leaves an open beaker containing 250.0 mL of a 0.500 M NaHCO3(aq) solution on a lab bench. They return a
aleksklad [387]

Answer:

1.67 M

Explanation:

The following data were obtained from the question:

Initial volume (V1) of solution = 250 mL

Initial Molarity (M1) of solution = 0.5 M

Final volume (V2) of solution = 75 mL

Final Molarity (M2) of solution =?

Thus, we can obtain the final molarity of the solution by using the following formula:

M1V1 = M2V2

0.5 × 250 = M2 × 75

125 = M2 × 75

Divide both side by 75

M2 = 125 /75

M2 = 1.67 M

Thus, the new Molarity of the solution is 1.67 M.
