What are the changes to an indicator when acids and alkali are mixed?
When acids and alkalis are mixed, the pH of the solution changes. Indicators such as litmus paper will change color based on the new pH. Acids turn blue litmus paper red, while alkalis turn red litmus paper blue.
When acids and alkalis are mixed together they?
They neutralize each other to form salt and water.
When acids and bases are mixed they what each other?
Acids have a pH from 7 to 0 and bases have a pH for 7-14. Water is neutral with a pH of 7. If an equal strength acid and base are mixed together they cancel each out out.
What is used to determine the pH of acid and bases?
A pH meter or pH indicator paper is commonly used to determine the pH of acids and bases. pH meters provide a numerical measurement of pH, while pH indicator paper changes color based on the pH level to give a visual indication.
How are acids and bases described in the pH scale?
Acids and bases are described in the pH scale based on their strength. For instance,lactic acid has pH 6,but curd,obtained from milk itself has pH 3! HCl is called as the "king of acids" with pH 1. {on the pH scale,if any substance has pH 7, its considered acidic, while anything above 7 is basic.} Acids or Bases can be considered as acidic or basic by the colour changes in the pH scale{eg:red to orange[neutral]to violet}.

What is the colour change when onion solution is added to acids and bases?
When onion solution, which contains anthocyanins, is added to acids, it typically turns a reddish color due to the lower pH. In contrast, when mixed with bases, the solution changes to a greenish-yellow hue as the pH increases. This color change is a result of the pH-sensitive nature of the anthocyanins present in the onion.

What does the ability of a solution to resist changes in pH depend on?
The ability of a solution to resist changes in pH, known as buffer capacity, primarily depends on the presence and concentration of weak acids and their conjugate bases (or weak bases and their conjugate acids) in the solution. These components can react with added acids or bases to neutralize them, thus minimizing pH changes. Additionally, the overall concentration of the buffering species influences how effectively a solution can maintain its pH when subjected to external changes.
What indicator do the fire brigade use for acids?
The fire brigade typically uses pH paper or litmus paper to determine the acidity or basicity of a substance, including acids. pH paper changes color based on the pH of the substance applied to it, helping responders to quickly identify if an acid is present.
Is it true buffers are weak acids or bases that can react with strong acids or bases to prevent sudden changes in pH?
TURE
What is the process where acids and bases mixed to form pH that is neutral?
This process is called as neutralization of an acid and a base.
What is a chemical dye that changes color based on the pH of a solution called?
A chemical dye that changes color based on the pH of a solution is called an pH indicator.
