What are three safe methods to test for an acid?
1. Test with a pH paper. 2. Test with a liquid or solid pH indicator. 3. Measure the pH with a pH-meter.
Is pH an absolute or a relative measure explain?
pH is an absolute measure which is used to get the details about both acid and base level of any liquid products. It is an absolute measure because the scale never changes.
What if an empty graduated cylinder weighs 51.36g. When filled with 50.0mL of an unknown liquid. it weighs 91.35g. What is the density of the unknown liquid?
A gram is a measure of mass, not of weight. The density of the liquid is 0.8 grams per mL.
What is the pH of sulphur and nitrogen?
Sulfur is not soluble in water and it depends on the form the phosphorous takes as to what it will do in water, or air, for that matter. Liquid nitrogen does not have pH. pH is based on the measure of the molar concentration of hydrogen ions in solution - there are no hydrogen ions in liquid nitrogen.
How do you identify an aqueous solution as acidic basic or neutral based on its pH value?
The pH of a liquid is a measure of its acidity. If a liquid has a pH of less than 7 in is acidic. If it is more than 7 it is basic. If it has a pH of 7 it is neutral. pH can be measured with chemical indicatior or with a pH meter. In the "related links" below is an image from Wikipedia that shows the pH of some common substances.
What does a pH meter do?
measure the pH of a liquid and possibly a solid
What scale is used to measure acidity in a liquid?
PH scale
Describe how you would measure PH of an unknown liquide?
Add universal indicator.
Could universal indicator be used to identify a liquid as being pure water?
A pH indicator is used only to measure the pH of the solution.

How could you lower the pH of the unknown liquid?
You should NEVER add acid (lowering pH) to an unknown liquid (or solid as well), it can be very dangerous. For example: suppose the unknown happens to be hypochlorite (bleach powder solution, desinfectant): when you add acid (any will do) then CHLORINE gas might escape which is a VERY TOXIC gas, causing acute pulmonary (o)edema.

What can be used instead of phenolphthalein to measure pH?
Litmus paper, or other pH papers can measure pH. Many pH test papers can measure specific pH values. There are also instruments called pH meters that can measure pH.
