How can you find the density of an unknown liquid?
To find the density of an unknown liquid, you can measure its mass using a scale and then measure its volume by using a graduated cylinder or displacement method. Divide the mass by the volume to calculate the density of the liquid.
Explain how can you find the density of an unknown liquid if you have all of the laboratory equipment you need?
To find the density of an unknown liquid, you would first measure the mass of a known volume of the liquid using a balance. Then, you would measure the volume of the liquid using a graduated cylinder. Finally, divide the mass by the volume to calculate the density 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 would you measure the pH of an unknown colourless solution?
You can measure the pH of an unknown colorless solution using a pH meter or pH paper. Simply dip the pH meter probe or pH paper into the solution and observe the reading or color change to determine the pH level of the solution.
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.
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.

Is pH an absolute or a relative measure?
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.

You can measure the pH of an unknown colorless solution using a pH meter or pH paper. Simply dip the pH meter probe or pH paper into the solution and observe the reading or color change to determine the pH level 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 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
