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.

How can you measure the pH of an unknown liquid?
You can measure the pH of an unknown liquid using a pH meter or pH test strips. Simply dip the pH meter or test strip into the liquid and observe the reading or color change, respectively. This will give you an indication of the pH level of the unknown liquid.
What is pH of a liquid?
pH is a measure of how acidic or basic a liquid is on a scale from 0 to 14, with 7 being neutral. A pH below 7 indicates acidity, while a pH above 7 indicates alkalinity. The lower the pH, the more acidic the liquid.
How could you raise the pH of an acid like vinegar to a neutral or higher pH?
lower PH
What would be most useful for identifying an unknown liquid?
Conducting tests such as determining its boiling point, density, and pH level would be helpful in identifying an unknown liquid. Additionally, using techniques like chromatography or mass spectrometry can provide further insights into the composition of the unknown liquid.
Does liquid chlorine raise or lower Ph?
Liquid chlorine raises the pH since liquid (sodium hypochloride) tablet or granular (calcium hypochloride) are basically alkaline, continued use increases the pH above 7.6. to counteract this an acid must be used.
How could you check if a liquid was pure water?
find the PH of it
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.
What is the pH of a liquid?
The pH of a liquid refers to the concentration of hydrogen ions in a liquid. (technically, it is the concentration of the hydronium ion H3O+ in a liquid in units of moles per litre) This is not a direct value however, pH is actually equal to -log10(moles/litre of hydrogen). This means that if you have 1x10-7moles/litre of hydrogen ions in the solution, your pH will be pH=-log10(1x10-7)= 7 Because of the nature of this scale, more acidic liquids have a lower pH than less acid liquids. For example, stomach acid is around pH 1.4, water is pH 7, and the digestive juices in the intestine are around pH 8.
Describes a solution with a pH lower than the pH of distilled water?
A solution with a pH lower than that of distilled water would be acidic. This could be achieved by adding an acid such as hydrochloric acid or sulfuric acid to water. Acidic solutions have a pH below 7, with the lower the pH, the more acidic the solution will be.
What is the PH of liquid phenol?
The pH of liquid phenol is typically around 6 to 7, indicating that it is slightly acidic. However, phenol can act as a weak acid, and its pH can vary depending on its concentration and the presence of other substances. In concentrated solutions, phenol may exhibit a lower pH due to its acidic properties.
What pH does a netutral liquid have?
the pH of a neutral liquid, which is water, is neither acidic or basic, therefore it pH value is between 7and8 or 7.5 in the ph scale
How could HCI be used in a swimming pool?
To adjust pH and/or lower alkalinity.
