Phenolphtalein indicator is colorless in dilute acid solution and basic solutions will turn its color (puplish) red.
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.
To determine the pH of a substance using the pH method, you will need a pH meter or pH strips. For a pH meter, simply immerse the electrode into the substance and wait for the reading to stabilize. For pH strips, dip the strip into the substance and compare the color change to the provided chart to determine the pH value.
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.
Yes, universal indicator can be used to determine the strength of acids and bases. It changes color over a range of pH values, allowing you to estimate whether a substance is an acid or a base and roughly how strong it is based on the color change. However, it is not as precise as using pH paper or a pH meter for accurate pH measurements.
A titration reaction is a chemical technique used to determine the concentration of a substance in a solution. It involves the gradual addition of a known concentration of another substance, called the titrant, to the solution until a reaction is complete. The endpoint of the reaction is usually detected using an indicator or an instrument, allowing for the calculation of the concentration of the unknown substance.

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.

an indicator is capable of determining if a substance is basic or acidic or neutral. if you are just looking for if it is a basic or acidic. then you could you could use red litmus or blue litmus. if you are looking for the pH of a substance try using: red cabbage indicator phenolphthalein i hope i answered your question!

If a substance is not pure, the density may, or may not, change, compared to the pure substance.
To determine the density of a substance using temperature and pressure, one can use the ideal gas law equation, which relates the density of a gas to its temperature and pressure. By measuring the temperature and pressure of the substance, one can calculate its density using this equation.
by using an indicator like litmus paper!!!
Below 100 °C.
To determine the density of a substance using pressure and temperature values, you can use the ideal gas law equation, which is PV nRT. By rearranging this equation to solve for density ( n/V), you can calculate the density of the substance by dividing the mass of the substance by its volume.
