potassium chloride
Concentrated HCl is hydrochloric acid with a concentration that is close to the maximum amount of this acid that can be dissolved in water. In general, it is considered to be approximately 12M, which is 12 moles of acid per L of solution, however 38-40% acid solution of concentrated HCl do exceed 12M (up to 12.6M). I am not sure of what happens if you try to make a solution of HCl that is more concentrated. In any case, you should always read the label on the bottle and consider the age of the mixture as pure HCl is a gas and will evapourate, which will lower the concentration.
Add More Salt to make it more concentrated and add more wtaer to make it less concentrated
If concentrated sulfuric acid spills on a surface, it should be immediately cleaned by first neutralizing it with a base such as sodium bicarbonate or calcium carbonate. This will help to neutralize the acid and reduce its corrosive properties. Afterwards, the area should be rinsed thoroughly with water and appropriate protective equipment should be worn during the cleaning process.
Add no more than 2 ml concentrated nitric acid slowly to 98 ml ethanol (industrial methylated spirit). Label the solution highly flammable but do not store longer than a week
You can mix a basic solution with a pH higher than 7 with a pH 2 solution to yield a neutral mixture. The basic solution should be strong enough to neutralize the acidity of the pH 2 solution. Common bases like sodium hydroxide or potassium hydroxide can be used for this purpose.
B. Report the spillage to your security POC.
Report the spillage to your security POC.
you should add more of the solute to the solution to make it more concentrated and more of the solvent to the solution to make it diluted.
Assuming you mean a solution of salt, you would add WATER.
Yes, a concentrated solution should be able to kill mold. Bleach also is an excellent mold killer.

No, suspensions and solutions are two different things. In a solution, the particles break down into molecules, and the molecules are broken down into ions, and these mix and bond with the molecules of the solvent. In a suspension, the particles remain exactly as they are, floating in the fluid.
When just enough strong acid (e.g. HCl) is used to neutralize a strong base (NaOH), the pH should be neutral (pH = 7.0).

A 50/50 mix of Propylene Glycol (concentrated engine coolant) should do the trick.
