You can use pH strips.
An acid will turn a blue strip red, and a base will turn a red strip blue. Then, there are strips that measure from 0-14. It changed color based on the strength of the acid or base. The most acidic material will measure out at 0 and turn the strip red, and neutral is yellow. Strong bases will be either blue or purple.
What else can I help you with?
Which indicator is used in titration for strong acid?
For the titration of a strong acid, the indicator typically used is phenolphthalein. Phenolphthalein changes color in the pH range of 8.2 to 10, which is suitable for titrating a strong acid with a strong base to determine the equivalence point.
What are the examples of acid base titration?
Determination of the concentration of a base by titration with acids or determination of the concentration of an acid by titration with bases. (http://en.wikipedia.org/wiki/Acid-base_titration)
Explain how the relationship between the strengths of an acid and its conjugate base and of a base and its conjugated acid?
If acid is strong then its conjugate base must be weak, if conjugate base is strong it again accept the H+ ions so acid can neither be strong, similarly if base is strong its conjugate acid must be weak.
Why neutralize alcohol with phenolpthalein?
Phenolphthalein is used as an acid-base indicator to determine the endpoint of a titration between a strong base and a weak acid when neutralizing alcohol. The pink color change indicates that all the weak acid has reacted with the strong base, allowing for accurate titration.
Is the conjugate of a strong base is a weak acid?
NaHCO3 is a weak base, with a conjugate acid of H2CO3+.

Can oxalic acid be used for standardization of strong base?
Yes, in fact it is the only acknowledged acid (DIN, ASAC, NEN) to be used with standardisation in analytical titration chemistry (volumetrics > > titrimetrics > acidimetry). By the way, it is also used in oxidimetric standardisation.
What is formed when a strong acid with a strong base?
A salt is formed when a strong acid reacts with a strong base.

What products are produced in a neutralization reaction between a strong acid and a strong base?
Strong Acid + Strong Base ---> Neutral Salt + Water
How do you determine if a conjugate acid or base will be strong or weak?
A weak acid/base will have a stronger conjugate base/acid. The conjugate acids/bases of strong bases/acids are very weak because they have no attraction to protons or hydroxides, which is why the reaction shifts all the way to the right and the Ka/b is large.
Will the solution at the end point of an acidbase titration be acidic neutral or alkaline if it is a weak acid and strong base?
The solution at the endpoint of an acid-base titration involving a weak acid and a strong base will be alkaline. This is because the weak acid will have been neutralized by the strong base, resulting in excess hydroxide ions in the solution causing it to be alkaline.
Is H2SO4 a base?
No, H2SO4 (sulfuric acid) is not a base; it is an acid. It is a strong acid that donates protons in aqueous solutions.
What is the counter base for a strong acid?
For countering a strong acid, a strong base like NaOH, LiOH are required.
