It is known that the HCl solution has a molar concentration of 0.10 M, and it's volume is 25 ml. First we convert the 25 mL to 0.025 L, next we multiply 0.025 L with 0.010 M to find the number of moles of HCl (because Molar concentration = mole/litre), which is 0.0025 moles. When diluted, HCl dissociates to H+ and Cl- ions,

A person experiences `acid stomach' when this concentration rises to about 0.100 Molar. Then you figure out how many moles you have left and calculate molarity.

If you take a sample of pure water, there will be few hydroxide and hydronium ions. Of course, they can combine to form water and yes they do combine but there will be few water molecules which break/combine to form the ions again. Hence, there exists a dynamic equilibrium between concentration of.

pH is a way to express the concentration of the hydrogen ions (H +) in a solution. In chemistry, one common way of expressing a concentration is grams of a substance.
