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.
The ph of a substance can be determined by using a device called what?
If the substance is in liquid form, the pH may be determined by litmus paper.
How is the endpoint of a titration between H3PO4 and NaOH determined?
The endpoint of a titration between H3PO4 (phosphoric acid) and NaOH (sodium hydroxide) is determined by using an indicator that changes color when the reaction is complete. This indicator helps to visually identify when the acid and base have reacted in the correct proportions, indicating the endpoint of the titration.
How do you determine if a substance is an acid or a base using phenolphtalein indicator?
Phenolphthalein is colorless in acidic solutions and pink in basic solutions. By adding phenolphthalein to a substance, you can observe the color change to determine if the substance is acidic or basic based on the change in color.
Do you need to have water present to see if something is an acid or an alkali?
hi im just starting a level chemistry and i am not aware that you need water to find out if something is acid or alkali, you could use a indicator such as universal indicator or methyl orange and so on, or you could use indicator paper. If this helps good, if not sorry. Jack

You can find the pH of a substance by using?
using a pH meter or pH indicator strips, which change color depending on the acidity or alkalinity of the substance. Another method is using universal indicator solution that changes color at different pH levels, allowing you to estimate the pH of the substance based on the color observed.
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.
Can strong and weak acids and strong and weak bases be determined by using an indicator?
yes
The ph of a substance can be determined by using a device called what?
If the substance is in liquid form, the pH may be determined by litmus paper.
A property of matter that can be observed and measured with out changing its density?
One property of matter that can be observed and measured without changing its density is its color. The color of a substance can be determined visually or quantitatively using instruments like a spectrophotometer, without altering its density.
A student determined the mass and volume of a gold ring. What physical property of the gold can be determined using these two measurements?
Its density can.
What physical property of gold can be determined by using mass and volume?
The density of gold can be determined by using its mass and volume. Density is a physical property that describes how tightly packed the material is. Gold has a relatively high density compared to other common metals.

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.
Is viscosity a qualitative or quantitative properties and why?
Viscosity is a quantitative property because it can be measured using physical units such as pascal-seconds (Pa·s) or centipoise (cP). It represents a fluid's resistance to flow and can be precisely determined through experimental methods, making it a quantifiable characteristic of the substance.
