According to the phase diagram for water, how is the state of water determined?
joja [24]

Explanation:

From the attached phase diagram, one can easily make out the phase in which water exists. Matter generally exists in three physical states which are solid, liquid and gas. Water is a unique compound that can exists in these three states at a given temperature and pressure.

From the attached phase diagram,

  1. point O is the triple point where the three phases of pure substance co-exists.
  2. The areas between the curves points at a single phase of matter. Y is a water vapor.
  3. The lines on the curve denotes two equilibrium phases. For example; X is a phase contain ice and melt water.

[please answer fast!] If the hydroxide ion concentration is 2x10^-3 M, what is the pH of the solution? Show your working.
Verizon [17]

Answer:

pH = 11.30

Explanation:

pH is defined as -log [H⁺]

To find [H⁺] from [OH⁻] -Concentration of hydroxide ion-, we must use the equilibrium of water:

H₂O(l) ⇄ H⁺(aq) + OH⁻(aq)

Keq = 1x10⁻¹⁴ = [H⁺] [OH⁻]

[H⁺] = 1x10⁻¹⁴ / [OH⁻]

[H⁺] = 1x10⁻¹⁴ / 2x10⁻³M

[H⁺] = 5x10⁻¹²M

pH = -log (5x10⁻¹²M)

<h3>pH = 11.30</h3>
