How do certain substances affect the pH level of tap water?
Acidic substances will lower pH and more alkaline or basic substances will put it above the neutral value of pH = 7
What is the way a person can distinguish among acids bases and neutral substances?
The simplest method is to determine the pH with a pH-paper or a pH-meter.
Does higher PH acidity mean it is safer than all of the other lower PH substances?
The closer it is to neutral (7) the safer it is.
What common household substances are neutral?
All substances can be classified as an acid,base or neutral substances.Neutral subtances are the substances that are niether acids nor alkali (bases in solution).Therefore they are safe to drink and use.they have a pH of 7 while acids have a pH less than 7 and bases have a pH more than 7.neutral substances have equal concentration of hydrogen ions(H+) and hydroxide ions(OH-).Examples of neutral substances are water,salt,sodium chloride,calcium chloride,potassium nitrate,ammonium nitrate copper sulphate,magnesium sulphate calcium carbonate.
How do you calculate how much base to add to increase the pH of the solution?
This depends on what other acids or bases or buffering substances are in solution already, even if pH is neutral!
What is the ph of neutral substances?
7
What do we give to substances that are not acids or alkalies?
Substances that are not acidic or alkaline are neutral in their pH. Lots of substances exhibit a slight variance from a pH of 7, which is neutral. We don't notice many of them because they aren't far from neutral.
What is the pH number for neutral substances?
7
What are pH strips?

What compounds have a pH valu of 7?
The compounds that are neutral in nature have a pH of 7. These substances are neither acidic nor basic.
What is the pH level of salt added to water?
If it is common salt ( sodium chloride) the pH should not alter as they are both neutral substances at pH = 7.
