The concentration of Hydronium ions (H3O+) in moles/liter. They used to teach concentration of H+ ions, but since Hydrogen without an electron is just a lone proton, scientists have determined that lone protons won't just stay that way but will tend to 'want' to bond with a water molecule, forming the hydronium (H3O+).
A concentration of 10-7 moles per liter is considered neutral. pH is -log(hydronium concentration) so this is equivalent to a pH of 7.
- If the concentration of hydronium is higher than 10-7 mole/liter, then the solution is acidic (pH less than 7).
- If the hydronium concentration is less than 10-7 mol/liter (pH > 7) then it is a base.
put a drop of solution on litmus paper if blue litmus changes to red then it is acedic or if the red litmus paper changes to blue then it is basic.
if there is no colour change on both the cases then it is neutral.
There is a cool java tool from the University of Colorado that I posted in the related links.
What else can I help you with?
What can litmus paper tell you about a solution?
Litmus will allow you to tell if a solution is a acid or a base.
What quantity can tell you whether a solution is acidic or base?
The pH level of a solution is a measure of how acidic or basic it is. A pH below 7 indicates acidity, while a pH above 7 indicates alkalinity (basicity). A pH of 7 is considered neutral.
How does diluting an acidic or basic solution affect the pH of the solution?
It depends on the pH of the dilutant. if the dilution substance is base the acidic solution will become less acidic moving toward neutral pH, the more it is diluted the less acidic it will become. A base solution will remain base or about 7 pH
The measure of how acidic or basic a solution is?
The measurement for how acidic or base a solution is called pH level. The pH level is on a scale from 1-14. One being very acidic, 7 being neutral, and 14 being very base.
What determines whether a substance is an acid or base?
The presence of hydrogen ions (H+) determines if a substance is an acid. Acids release H+ ions in solution. Bases, on the other hand, release hydroxide ions (OH-) in solution or accept H+ ions.
What determines whether a soulition is acidic or base?
just put a drop of solution on blue litmus paper. if litmus turn in to red color then solution is acid otherwise it is base .
What determines the properties of solution?
Whether or not it's an acid or a base
What DETERMINES properties of a solution?
Whether or not it's an acid or a base
What determines if a substance is acidic or base?
a pH scale.
What can litmus paper tell you about a solution?
Litmus will allow you to tell if a solution is a acid or a base.
Is vinegar base?
Vinegar is an acidic solution.
Is a solution acid or base?
A solution may be acidic basic or neutral.
When would litmus paper be useful?
It helps in indicating whether a substance is acidic or basic A red litmus paper turns blue in basic solution and turns red in acidic solution A blue litmus paper turns red in acidic solution and turns darker blue in basic solution
What quantity can tell you whether a solution is acidic or base?
The pH level of a solution is a measure of how acidic or basic it is. A pH below 7 indicates acidity, while a pH above 7 indicates alkalinity (basicity). A pH of 7 is considered neutral.
What happens when the pH solution is lower?
When adding a strong acid to an acidic solution pH decreases. Adding a strong base to an acidic solution the pH increases.
How does diluting an acidic or basic solution affect the pH of the solution?
It depends on the pH of the dilutant. if the dilution substance is base the acidic solution will become less acidic moving toward neutral pH, the more it is diluted the less acidic it will become. A base solution will remain base or about 7 pH
