there are more H+ ions in a pH 2 solution that in a pH 4 solution. The hydrogen ion (H+ ion) is responsible for the acidity of a substance and so, the more of it there is, the more acidic it is (higher acidity= lower pH) :)
No it is false -it has a high concentration of H+ ions
Baking soda is a chemical compound with the formula NaHCO3. It does not contain hydrogen ions in its structure; instead, it contains a sodium ion, hydrogen carbonate ion, and oxygen. When baking soda dissociates in water, it releases hydrogen ions, but the number of hydrogen ions released depends on the concentration of the solution.
pH is -log10[H3O+]; the negative logarithm (with base 10) of the hydronium concentration (hydrogen ions do not float around on their own. Instead they attach to a water molecule and become a hydronium ion).
You can dilute by adding distilled water. When diluting, be sure to add the solution to water several times instead of adding water to the solution (especially if it is highly concentrated).
ZnCl2 does not exhibit acidic properties in water because it does not release hydrogen ions (H+) to form an acidic solution. Instead, it forms a neutral solution when dissolved in water.

It's not that the concentration of H+ ions goes up because pH goes up. Instead, the pH goes down because H+ concentration increases. I know that's a really subtle difference, but it is crucial. If you're good at math this may help: pH= -log [H+] where [H+] simply means concentration of hydrogen ions. So, you can see from this formula that as the concentration of hydrogen ions increase, the pH will decrease because it is a negative log. You can also see that the pH is a function of hydrogen concentration. I hope that clears some ideas up for you. Good luck!

The pH scale provides a more convenient way to express the concentration of hydrogen ions in a solution using a logarithmic scale that covers a wide range of values. It allows us to easily compare the acidity or basicity of different substances without having to work with large concentration numbers.

When an aqueous solution of sodium hydroxide is electrolyzed, hydrogen is produced at the cathode because hydrogen can be produced at a lower voltage than can sodium, and the supply of hydrogen from the water of the solution is sufficient to consume all the current supplied. When molten sodium chloride is electrolyzed, however, sodium is produced at the cathode.
when an aqueous solution is used, hydrogen gas is evolved at cathode, instead of depositing sodium metal.
Usually hydrogen will evolve from the cathode and oxygen from the anode, but if zinc is the anode, it may dissolve to produce zinc ions in the solution either instead of or along with oxygen evolving.
pH is not really something that can be found, but instead measured. pH stands for the potentiometric concentration of hydrogen ions and is a measurement of the acidic or basic qualities of a solution. The pH scale ranges from 1-14 where 1-6 are acidic 7 is neutral and 8-14 are basic. The farther away from 7 you get in either direction the more highly acidic or highly basic a solution is.
Medical establishments typically use percent concentration instead of molarity because percent concentration provides a more intuitive understanding of the amount of drug or substance in a given volume. This can be easier for healthcare professionals and patients to comprehend compared to molarity, which involves more complex calculations related to the molar mass and volume of a solution.
