Good question. Some materials are more soluble in one solution than another.
In general (very general); non-polar things are soluble in non-polar solutions.
Polar things are soluble in polar solutions.
So - for example - salt is NaCl, which is Na+ Cl- and so very polar. It dissolves well in water because water is also polar. (Water is kinda like H+ O- H+ if you excuse the poor charge balancing for the sake of simplicity).
Paint however may be (not always, you can get water soluble paints) very non-polar and so you need something non-polar to dissolve it. White spirit is made from aliphatic (and alicyclic) compounds...which means hydrocarbons. These are not polar since C and H are actually pretty close in terms of electronegativity and they have no overall charge.
And so when you put white spirit on the paint, the paint dissolves into the white spirit and so the paint "comes off".

For more advanced understandings, perhaps start looking into thermodynamics and the hydrophobic effect as they pair up nicely and kind of help each other in terms of understanding.

How do titanium dioxide reacts with nitric acid?
Titanium dioxide does not react with nitric acid under normal conditions because it is a stable compound. To react with nitric acid, titanium dioxide would need to be in a reduced form, which is not its natural state. If titanium dioxide is in a reduced form, it can react with nitric acid to form titanium nitrate and water.
What are some common compounds titanium can be found in?
Titanium can be found in compounds such as titanium dioxide (TiO2) used in sunscreen, paint, and food coloring; titanium tetrachloride (TiCl4) used in the production of titanium metal; and titanium sulfate used in the treatment of water and wastewater.
What will take place if titanium dioxide is reacted with hydrochloric acid?
When titanium dioxide is reacted with hydrochloric acid, titanium chloride and water are formed. This reaction typically produces a white precipitate of titanium chloride, while the excess hydrochloric acid remains in the solution.
How does titanium react with water and oxygen?
Titanium is inert to water at room temperature due to the formation of a protective oxide layer on its surface. When exposed to oxygen, titanium readily forms a thin layer of titanium dioxide, which further prevents corrosion and protects the metal from further oxidation.
What is the chemical name of titanium dioxide?
They are also known as acidic oxides since they form acidic solutions in water.
What is titanium dioxide pH?
Titanium dioxide is not dissolved in water.
What is white spirit used for?
Why can't water wash paint of which has titanium dioxide but white spirit can?because the water has titanium dioxide in it so white spirit contains alcohol which is different than waterby me love you any more questions comment under this Thanksbye:* :)

Why can you get paint off with white spirit and not water?
Spirit based is oil based and oil and water don't mix. Use paint thinner or mineral spirits.

Is titanium dioxide water soluble?
Titanium is an unsoluble metal, like ALL metals. Some are able to react with water (alkali metals) but that's something different from solubilization
How can I make whitewash paint?
To make whitewash paint, mix hydrated lime with water until it forms a thin, smooth consistency. Add salt to help the mixture adhere better. Optionally, add pigment like titanium dioxide for a brighter white color. Apply the whitewash paint to surfaces like wood or brick for a traditional, rustic look.
How titanium dioxide crystals on noxer block catalyse oxidation reaction that remove NOx from the atmosphere?
Titanium dioxide absorbs the radiation which is given off from the sun. This excites the electrons in titanium dioxide to a higher energy level. The high energy electron from titanium dioxide reacts with oxygen to produce a superdioxide ion on the surface of the titanium dioxide crystals; O2 +e- O2- Water also reacts with the oxide to produce a hydrogen, hydroxyl radical and an electron which is given back to the titanium dioxide; H2O + O2 H+ + OH + e- "The overall reaction is therefore; H2O + O2 H+ + O2- + OH" The hydroxyl radical formed can then oxidise nitrogen dioxide to nitrate ions because it is a very powerful oxidising agent; NO2 + OH H+ + NO3- More of the nitrogen gases can be rendered as the superoxide produced on the surface of titanium oxide can be used to convert nitrogen monoxide into nitrate ions; NO + O2- NO3- Titanium dioxide absorbs the radiation which is given off from the sun.
