A pH indicator will test a substance to determine the alkali or acidity, with 7 being neutral on the pH scale.
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.
If the substance is in liquid form, the pH may be determined by litmus paper.
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.
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.
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

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 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.
yes
If the substance is in liquid form, the pH may be determined by litmus paper.
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.
Its density can.
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.

Atoms are too small to count and there are too many of them.
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.
