Which property of a substance can be determined using a pH indicator?
The acidity or alkalinity of a substance can be determined using a pH indicator. pH indicators change color depending on the pH of a solution, allowing for the determination of whether the substance is acidic, neutral, or basic.
How specific gravity measured?
Specific gravity is measured by comparing the density of a substance to the density of a reference substance (usually water). It is typically determined using a hydrometer or a densitometer. The specific gravity of a substance is a unitless value that indicates how much denser or lighter the substance is compared to water.
How can one determine electrical conductivity in a material or substance?
One can determine electrical conductivity in a material or substance by measuring its ability to conduct electricity. This can be done by using a device called a conductivity meter or by performing a simple experiment to test the material's conductivity.
What property of a substance can be determined using a pH indicator?
The acidity or alkalinity of the substance can be determined using a pH indicator. pH indicators change color based on the pH of a solution, helping to identify if a substance is acidic, neutral, or alkaline.
How can electrical conductivity be measured accurately and efficiently?
Electrical conductivity can be accurately and efficiently measured using a device called a conductivity meter. This device measures the ability of a substance to conduct electricity by passing a small electrical current through it and measuring the resulting conductivity. The conductivity meter provides a numerical value that indicates the conductivity of the substance being tested.

How can opacity be accurately measured?
Opacity can be accurately measured using a device called a nephelometer, which measures the amount of light scattered by particles in a substance. This measurement provides a quantitative value for the opacity of the substance.

Why must the number of atoms in a substance be determined using mass and not by counting?
Atoms are too small to count and there are too many of them.

When using electronics what device is capable of changing DC to AC?
A device called a power inverter.In old vacuum tube radios an electromechanical device called a vibrator was used.Another device is a motor-generator using a DC motor and an AC generator.
Density is a measurable property of matter. How can the density of a substance be determined?
Density can be calculated by dividing the mass of a substance by its volume. Mass is typically measured using a balance, while volume can be determined through various methods such as displacement or geometry. The resulting value represents how much mass is present in a given volume of the substance.
How do you get a duck out of the pool?
Using a device called a duck hook pole
Is qualitative determination using gas chromatography the best separation technique?
The quantity of a substance separated by gas chromatography can be determined by its?
Why is an inductor called as passive device where as a resistor is called active device?
They are both passive devices. An active device is a device that uses semiconductors (or tubes) to process signals instead of using the natural processes of capacitance, inductance or resistance.
