Can universal indicator be used to determine the strength of acids and bases?
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.
What is used to identify an acid or a base?
A pH indicator is commonly used to identify whether a substance is an acid or a base. Acids turn pH indicators red, orange, or yellow, while bases turn them green, blue, or purple. pH paper strips can also be used to determine the acidity or basicity of a substance based on the color change.
How can one determine the pH of a weak acid?
To determine the pH of a weak acid, you can use a pH meter or pH indicator paper. Alternatively, you can calculate the pH using the concentration of the weak acid and its dissociation constant.
How can one determine the pH of a strong acid?
To determine the pH of a strong acid, you can use a pH meter or pH paper. Simply dip the pH meter probe or pH paper into the acid solution and read the pH value displayed on the meter or color on the paper. Strong acids have a pH value below 7, indicating acidity.
What is added to an acid to maintain its pH?
A base is added to an acid to maintain its pH. Bases help neutralize the acidic solution by accepting hydrogen ions, thus raising the pH level closer to neutral. Common bases used for this purpose include sodium hydroxide and potassium hydroxide.

What is the differentiate acid and bases?
An acid is below 7 on the pH scale and bases are above 7 on the pH scale. An acid can be a hydrogen donor, and a base is a hydrogen acceptor.
How would you compare acids and bases in terms of their pH?
acid pH < 7base pH > 7
What scale is used to determine whether a solution is an acid or base?
When referring to acidity of a solution one uses the pH scale. The lower the number, the higher the acidity. Pure water is said to be neutral, and is a 7 on the scale. Anything with a lower number ranking is acidic, and anything with a higher ranking is basic.
What value is used to express the acidity or alkalinity of a system?
Normally term,'PH' of a solution is used determine the strength of an acid which is nothing but the concentration of H+ ion concentration in a solution. ph= -log[H+] concentration.... since its -ve log hence smaller value of PH means it's more strong acid. ph=7 is value of water which is neutral. pH ranging below 7 are acids & above 7 are bases.

What is the effect of phenopthelin on bases?
Phenolphthalein does not directly interact with bases. It is a pH indicator commonly used in titrations to determine the endpoint of an acid-base reaction, where it changes color depending on the pH of the solution. It remains colorless in acidic solutions and turns pink or purple in basic solutions.
Is sharp a acid or alkaline?
Sharpness is a sensory perception related to taste and has nothing to do with being an acid or alkaline substance. pH is used to determine if a substance is acidic (pH below 7), neutral (pH of 7), or alkaline (pH above 7).
