the lower the pH of a solution the more alkaline it is the higher is more acidic. water usually has a pH of around 7.0

What is meant by number of replaceable ions?
it means the no of replaceable hydrogen atoms
How do you tell acid from a base?
There are a number of ways to tell an acid from a base. By definition, any solution with a pH lower than 7 is an acid, and if the pH is higher than 7 it is a base (if it is precisely 7 it is neutral and probably pure water). pH measures the level of hydrogen ions in a solution, but not in the way you might expect; a lower pH number means a higher amount of hydrogen ions and a lower amount of hydroxide ions, whereas a higher pH means less hydrogen ions and more hydroxide ions. You will observe that acids have hydrogen in their molecular formula; hydrochloric acid is HCl, sulfuric acid is H2SO4, and so forth, there is always an H. Bases have hydroxide, which is OH, in their molecular formula, so sodium hydroxide is NaOH. I realize that this could be confusing because hydroxide also contains hydrogen, so if you only look at the hydrogen, both acids and bases have it. But in a base, the hydrogen is connected to an oxygen, in the form of a hydroxide radical.
Dose water contain half as many hydrogen atoms as oxygen atoms?
No, the chemical formula for water is H2O. This means that for every oxygen atom in the compound, there are two hydrogen atoms. Thus, the number of hydrogen atoms in water is double the number of oxygen atoms.
Why was hydrogen named hydrogen?
In Greek, Hydro means "water", and Gen means "create." So hydrogen means "water-making." And it takes 2 hydrogen atoms combined with an Oxygen atom to create water.
What do the numbers mean on the back of glass paper?
it means the lower the number the ruffer it is but the higher the number the smoother it is!x
What does the pH scale monitor?
Acidity. Or in chemical terms, the concentration of hydrogen ions versus hydroxide ions. Greater [H+] means a lower pH. Greater [OH-] means higher pH. [H+]*{OH-] will always equal 10^-14.
What does it mean for a percent to be greater than 100 percent?
It means that the number that the percentage represents is greater than 1.It means that the number that the percentage represents is greater than 1.It means that the number that the percentage represents is greater than 1.It means that the number that the percentage represents is greater than 1.
What means 12 greater than a number?
It means to add 12 to the number.
Does a lower Celsius number mean colder?
Yes, it does. A lower number means a lower temperature.
The number 0 is a positive integer?
No. Positive means GREATER than zero.No. Positive means GREATER than zero.No. Positive means GREATER than zero.No. Positive means GREATER than zero.
What solutions have a greater number of hydroxide ions than hydrogen ions?
An acidic solution has a greater number of hydrogen ions than hydroxide ions. However, technically they are hydronium ions (H3O+), not hydrogen ions.
What affects absolute brightness?
Brightness corresponds to amplitude of waves. Greater amplitude means greater brightness (so lower amplitude means less brightness).
What greater than means?
A larger number. 4 is greater than 3.
What is the difference between greater than and greater than or equal to?
greater than means it will always be a larger number than said answer, like 2, meaning any number larger than two can be an answer.greater than or equal to means it it can be larger than two, but it can also be two.The same rules are for less than and less than or equal to.
Where H2 means a molecule of hydrogen and contains 2 atoms then number of moles is?
The molar mass of hydrogen is 2.
What is meant by number of replaceable ions?
it means the no of replaceable hydrogen atoms
What does more than mean in a math problem?
"more than" means "greater than". 100 is greater than 1 because it's a bigger number. 0 is greater than -3 because 0 is a greater number.
