What information about a chemical solution can be inferred from knowing its pH value?

See the answer below

Explanation:

The information than can be inferred from knowing the pH value of a chemical solution is the hydrogen or hydroxyl ion concentration of the solution.

The pH of a solution is the degree of acidity or alkalinity of the solution. Mathematically, the pH of a solution is expressed as:

pH =   where = hydrogen ion concentration.

Also,

pH = 14 - pOH, where pOH =

The more the of a solution, the lower the pH, and the more the of a solution the higher the pH. The pH value ranges from 0 - 14 with 7 being a neutral pH.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
