pH tells us the hydrogen ion (H+) ion concentration. The lower the number - the greater the number of hydrogen ions. Adding hydrogen ions decreases pH (and increases acidity) removing them (eg by adding hydroxide OH-) increases pH.

Why is the range of pH fixed?
pH is a function of the concentration of hydronium ions in a water solution and theoretically can take any number, not just the traditional 1-14 range. However there are physical limits to how much of this substance can be present in a solution without precipitating and this establishes the lower limit of pH. At the other end of the scale pH can be determined mathematically from the concentration of hydroxide ions, but this too is limited to a point, setting the upper limit for pH. These limits take the allowable pH range down to about -5 and up to perhaps 20.
Which way do horizontal lines go?
horizontal lines run from side to side... left to right or right to left... like looking out on the horizon
What force slows things down?
Friction, when moving sideways. Upthrust when you are trying to go down. gravity when you are trying to go up
Truefalse can friction slow things down?
true. Friction DOES slow things down. In fact, if there was no friction once something started moving it wouldn't be able to stop Friction can slow the things down. It's true.
What do these two parts of the lift do?
They lift the miners and their tools ..so that they can go up and down
How can you decrease the pH in your freshwater aquarium?
you can use pH up and pH down but it keeps going down and down if you pH is 8.0 its bad. if you have rocks in that are not chalking take a few out and try putting in bogwood it makes it go down to.
Will the pH of rain go up or down with pollutants in it?
The pH of rain will go down with the pollutants
Will the pH of the rainwater go up or go down with pollutants in it?
The pH of the rainwater will go updown,updown!
Which way does an acid pH go from neutral up or down?
down
Does a base donate a h ion?
Acid makes the pH number go up Bases makes the pH number go down
Can lemon cause the pH of a substance to be higher?
Lemons contain citric acid, so adding lemon to something probably makes its pH go down. A pH above 7.0 indicates a base is acting in a substance. And moving down the pH scale means something is becoming less basic and/or more acidic. It can make the pH higher if the pH is already extremely low, simply from dilution. Adding lemon juice to concentrated sulfuric acid would make the pH go up very slightly.
When you add an acid to an alkali does it make the pH number go up?
No it goes down
What makes the hot air balloon go up and down?
The hot air from the fire pushes the balloon up, and putting out the fire makes it go down again :)
What makes the governors go up and down?
centrifugal force
If a substance is added to water and the pH decreases is that substance an acid or a base?
pH of 1 to < 7 indicates an acid pH of >7 to 14 indicates a base pH of 7 indicates water
Why makes the sun come up and go down?
The sun does not go up and down. The earth rotates.
What is elevator in aircraft?
the elevator is what makes the the aircraft go up or down.
