If you’ve ever worked in a teaching lab, stocked a research bench, or mixed household solutions, a tidy list of common chemicals saves time and reduces guesswork. Having quick access to names, formulas and solubility helps when deciding what will dissolve, how to prepare solutions, and what safety steps to take.
There are 32 Solutes, ranging from Acetic acid to Urea. Each entry is organized with the columns Formula,Category,Solubility in water (g/100 mL at 20 C), so you can quickly match a compound to its chemical formula, type, and how much will dissolve at room temperature — you’ll find below.
What does “solubility in water (g/100 mL at 20 C)” tell me and how precise is it?
That value means grams of solute that dissolve in 100 mL of water at 20 °C; treat it as a practical reference rather than an absolute limit, since solubility changes with temperature, purity and experimental conditions — use it to estimate whether a compound will dissolve easily or require heating/solvent adjustments.
How can I use the Formula and Category columns when preparing solutions?
Use the Formula to confirm you have the correct chemical and the Category to understand chemical family, typical behavior and safety considerations; combine that with the solubility number to pick appropriate concentrations, solvents, and handling measures before preparing solutions.

Potassium chloride
A common source of potassium for fertilizers and medical electrolytes; dissolves in water to give K+ and Cl−. Used in agriculture, food processing, and as a low-sodium salt substitute in cooking.

Calcium chloride
Highly water-soluble de-icing agent and desiccant used in road treatment, dust control, and concrete acceleration. Dissolves to yield Ca2+ and Cl− ions and is used in food as a firming agent and electrolyte source.

Magnesium sulfate
Known as Epsom salt in its hydrated form; used in bath salts, laxatives, agriculture, and as a laboratory reagent. Dissolves to give Mg2+ and SO42− and is used medically for magnesium supplementation.

Ammonium nitrate
A highly soluble inorganic fertilizer and oxidizer used in agriculture and industrial explosives (with restrictions). Dissolves readily to give NH4+ and NO3− and is notable for its hygroscopic nature and nitrate supply.

Sodium bicarbonate
Baking soda; used in cooking, cleaning, antacids, and laboratory buffers. Moderately soluble in water, it releases bicarbonate ions and is used to neutralize acids or as a mild leavening agent.

Sodium carbonate
Known as soda ash; used in glassmaking, water softening, and cleaning products. Dissolves in water to give carbonate ions, raises pH, and is an important industrial alkali.

Potassium nitrate
A fertilizer and oxidizing agent historically used in gunpowder; dissolves in water to supply K+ and NO3−. Used in food curing, pyrotechnics, and some laboratory applications.

Copper(II) sulfate
Blue crystalline salt used as a fungicide, algicide, and laboratory reagent. Dissolves to give Cu2+ and SO42− ions; notable for its color and use in education for crystal demonstrations and copper chemistry.

Sodium hydroxide
Strong inorganic base used in soapmaking, chemical manufacturing, drain cleaners, and pH control. Highly soluble in water, producing strongly alkaline solutions and releasing heat on dissolution.

Hydrogen chloride
Hydrogen chloride is a gas that dissolves readily in water to form hydrochloric acid; widely used in chemical synthesis, pH adjustment, industrial pickling and household cleaners. In solution it supplies Cl− and strong acidity.

Carbon dioxide
