Answer:

Sodium-Potassium Pumps

Explanation:

Sodium-Potassium Pumps written as Na-K Pumps are ion channels found in the cell membrane of nerve cells. These pumps are responsible for maintaining the different ion concentrations across the membrane and help in polarization and depolarization of the membrane by influencing membrane potential. During ion exchange these pumps transfer three sodium ions from inside to outside of the cell and two potassium ions from outside to inside of the cell. In this way they maintain the ion concentration gradient across membrane.

MrRissso [65]

Answer:

6,97x10⁻³ gallons

Explanation:

pH is defined as:

pH = -log [H⁺]

Thus, you need to have, in the end:

10⁻⁷ = [H⁺]

And you have, in the first:

10^{-9,33} = [H⁺]

The volume of swimming pool is:

700'000 galllons ×\frac{3,78541 L}{1 gallon} = 2649787 L

Thus, the moles of H⁺ in the first and in the end are:

First:

10^{-9,33}mol/L × 2649787L = 1,24x10⁻³ moles

End:

10^{-7}mol/L × 2649787L = 0,265 moles

Thus, the moles of H⁺ you need to add are:

0,265 - 1,24x10⁻³ = <em>0,26376 moles</em>

These moles comes from 10M HCl, thus, the volume in gallons you need to add are:

0,26376moles*\frac{1L}{10moles}* \frac{1gallon}{3,78541L} =

<em>6,97x10⁻³ gallons</em>

<em></em>

I hope it helps!
