a wash
When the blue ink is added, it (eventually) spreads evenly throughout the water through diffusion. See related links below for more information.
it is not strong enough to harm
If red ink is mixed with water and heated, the ink will begin to dissolve in the water. The heat will increase the rate at which the ink molecules separate and mix with the water molecules. Eventually, the ink will completely disperse in the water, resulting in a colored solution.
Diluted salt water...
The ink would mix into the water and become diluted.

It is known as a wash, especially in water colour painting.
The amount of water needed to dilute 50ml of pigment ink depends on how strong or intense you want the color to be.

No, they are probably a mild diluted bleach.
This is the solvent in the ink (dye). Toluol and Xylol were common synthetics used as solvents but have now been replaced by safer chemicals such as cyclic alkylene carbonates. (this is the sweet smelling gas you detect) The solvent is the substance into which the dye is diluted. Water can also act as a solvent in ink. When released from the marker, the solvent evaporates and leaves the solid ink on the surface
I have used diluted anti-seize. Unfortunately it is not water soluble.
In the U.S. use diluted oxy clean, and hand wash the material
When you mix water with ink, the bubbles will go down to the bottom of the bottle and spin around. It may change colours like yellow, green, red or blue. There is no answer for this. It will make a interesting chemical reaction. Scientists are looking for a solution.

A standard ink cartridge is usually dye ink. Dye ink will run if used on glossy paper. But for photos on glossy paper pigmented ink is used and has more vibrant colors and usually more water proof.
