Calculate the pH and pOH of 0.010 mol OH- per liter

1 answer:

7 0

We can use a variety of formulas to determine our answers here.

Our formula for pOH is -log(mol), and we can plug it in as -log(0.010). Take note that OH- is a base, not an acid.

So, the pOH of OH- is 2.

To find pH we can set up this simple equation:
pH + pOH = 14
All we need to do is subtract 2 from 14, therefore the pH is 12.

This makes sense since acids range in the pH of 1-6, and we are dealing with a base. Hope I could help!

What type of relationship does temperature and pressure have?

blsea [12.9K]

Pressure is directly proportional to temperature.

From the ideal gas law- PV= nRT

by making P the subject of the formula, P= nRT/V

This implies that Pressure is directly proportional to temperature, OR, as pressure increases, temperature will increase proportionally.

The element oxygen has _____ valence electrons. (Input only a whole number, such as 7.)

kipiarov [429]

Remark
The short Answer is 6. That's why the ion has a charge of minus 2. Oxygen is doing it's best to have its outer ring have 8 electrons which is the number of outer electrons contained in the outer ring of the Noble Gas Neon.

Answer 6.

What type of reaction is pb(no3)2(aq) + 2kcl(aq) ® pbcl2(s) + 2kno3(aq)?

Sladkaya [172]

The given reaction is,

$Pb(NO_{3})_{2}(aq) +2 KCl(aq) --->PbCl_{2}(s) + 2 KNO_{3}(aq)$

In this reaction, the positive and negative ions of both the reactants rearrange resulting in the formation of new compounds. Such a reaction is referred to as the double replacement or the double displacement reaction. These type of reactions usually take place in aqueous medium and one of the products is a precipitate.

Double displacement reactions are of three types, precipitation reaction, neutralization reaction and reaction involving the formation of a gas. The given reaction is a precipitation reaction as one of the products is a solid.
