Ocean Types

Thought I list the types and see if I (we), can come up with scientifically valid reasons.

Molten:
1) molten metals
2) molten rocks
Warm:
1) salt water / alkaline metal ocean
2) iron-rich water, rust water
3) carbon-rich, which would be acidic
Cold:
1) liquid ammonia with water
2) liquid methane & ethane
3) liquid ammonia
4) liquid nitrogen

Note:
I did not include possible lifeforms. ie. Algae or bacterium growth. Even plants covering the surface of the ocean.
Hydrogen sulfide bacterium form pink colors. If they collect in gignormous numbers, could have pink oceans?

Also, this is just a generalization. Like Earth, at the bottom of the ocean in some parts, there are pools of molten sulfur.

Question on the rust water.
Could you have high concentrations of iron near the poles? Magnetic fields.

Lazarus has said that Venus' atmosphere can be considered a supercritical CO_2 ocean.

I'm guessing marasama is talking liquid oceans, not supercritical fluids (or other exotics like metallic hydrogen or superionic water that are thought to exist in giant planets) though.

This is very funny, I was just about to ask this question, but you already answered me. Anyway, I was going to ask more about the the possibility of hydrochloric oceans.

I also wanted to ask whether about complex and intelligent life. What is the likelyhood of either forming on a non-water based planet?

Hydrochloric Acid Oceans is possible. But I think it would have to be in the cold-earth analogs. Cause sunlight does a number on the chemical.

According to Wikipedia.
110 °C (383 K), 20.2% solution.
48 °C (321 K), 38% solution.

Sulfuric Acid on the other hand is at a higher temp.
But problems with acids is that they will corrode the land.
So, maybe concentration amounts is the answer, where the shoreline is more alkaline and the oceans are more acidic.

Yeah, I did not account for supercritical fluids.

The fact that chlorine planets orbit in the outer part of the habitable zone seems to be accurate. I found an article that explains chlorine worlds in great detail. Stating that:

Most often, a chlorine world is formed at the outer edges of a system's life zone, or even outside it. As the star ages and warms, or as the dynamic between the interplanetary material and the planets brings orbits closer to the primary, a chlorine world becomes possible.

but that

Most are extremely hot due to greenhouse effects (daytime temperatures of 30° to 50° Celsius are typical).

So you can see how I mistook how these worlds could be hot.
