What are the Characteristics you would look for to identify plasma substance
Vinil7 [7]

Plasma has similar physical characteristics to gas, in that it flows freely and drifts and separates to fill the container it's in. Plasma occurs at super high temperatures, this strips apart the molecules. It can also occur at relatively cool temperatures, this plasma has very charged particles. They are electrically neutral, as they often contain equal numbers of protons and neutrons. But they are still affected by electric and magnetic fields, because they are so free flowing.

This one is more like history then chem

How will the concentration of H+ and OH− ions change when a substance with a pH 11.4 is added to water?
PolarNik [594]

Answer is: H+ will increase and OH− will decrease.

pH = 11.4.

pH = -log[H+].

[H+] = 10∧(-pH).

[H+] = 10∧(-11.4).

[H+] = 4·10⁻¹² mol/L.

[H+] · [OH-] = 1·10⁻¹⁴ mol²/dm⁶.

[OH-] = 0.0025 mol/L.

pH value (potential of hydrogen - [H+]) is a logarithmic scale that specify the acidity or basicity of an aqueous solution.

When pH is greater than seven, aqueous solution is basic, below seven is acidic and when pH is equal seven, solution is neutral.
