Citric acid is a solid.
It is a solid. See the discussion page for further info. (It does not matter that it is dispersed, it still maintains its fundamental state of matter.) Citric acid (anhydrous) is a solid at temperatures below 153C (307F). Citric acid becomes liquid at 153C. At some temperature well above that, pure citric acid may enter vapor phase, but its likely the energetic state of atoms in the molecule at this temperature will cause it to come apart. The boiling point of a solution of citric acid in water depends on the concentration of citric acid in the water.
If two saturated citric acid solutions are made at the same temperature, they will always have the same concentration of citric acid. At a given temperature, the solubility of citric acid is fixed, resulting in solutions of the same concentration when saturated.
The saturation point for citric acid in water is around 59.2% at room temperature. This means that water can dissolve up to 59.2% of citric acid by weight at this temperature before reaching a point where no more citric acid can dissolve and the solution becomes saturated.
Citric acid is a white crystalline powder that is soluble in water and has a sour taste.
Salicylic acid is a solid at room temperature.

Liquid, because it's an acid.
Acetic acid is typically a liquid at room temperature.
Acetic acid is solid or in glacial state during winter
No, the concentration of a saturated citric acid solution depends on the amount of citric acid that can dissolve in the solvent at a given temperature. If the two solutions have different amounts of citric acid dissolved, their concentrations and volumes may vary.
This makes an endothermic reaction and a drop in temperature. When the baking soda is added to the citric acid it begins to bubble. After a few seconds the citric acid will stop bubbling and remain calm.
At room temperature some acids are liquids (sulfuric acid), some acids are solids (citric acid), and some acids are gases (hydrochloric acid; the liquid in the bottle labeled "hydrochloric acid" is actually a solution of the gas in water).
