Can strong and weak acids and strong and weak bases be determined by using an indicator?
yes
Easy Analytical techniques zinc sulphate Ferrous sulphate Copper sulphate through titration method?
For analysis through titration method: Zinc sulfate can be titrated using EDTA as the titrant. Ferrous sulfate can be titrated using potassium permanganate as the titrant. Copper sulfate can be titrated using sodium thiosulfate as the titrant.
Why does you use strong acid and weak base in titration?
Using a strong acid and weak base in titration allows for a clear endpoint to be reached quickly due to the pH change being more pronounced. This makes the titration process more accurate and easier to detect. Additionally, it minimizes the impact of any impurities or other weak acids or bases that may be present in the solution being titrated.
Why not using strong bases as active ingredients of antacid tablets?
Strong bases like sodium hydroxide or potassium hydroxide can be harmful to the stomach lining and may cause further irritation or damage. Antacid tablets typically use weak bases like calcium carbonate or magnesium hydroxide which are effective in neutralizing excess stomach acid without causing harm.
What does a base tast like?
Bases are often bitter tasting and have a slippery texture. However using taste and/or touch to identify a base is not recommended ,because touching or consuming a strong base is dangerous.
What are the reasons for the using glass-stopper bottles for acids and plastic stoppered bottles for bases?
If strong bases are present in the glass-stopper bottles, they may react with the glass and etch it or change the concentration of the base. Hence plastic-stopper bottles are used for bases.
A 0.361 molar solution of the weak acid HA with a pKa of 4.039 is titrated with a 0.163 molar solution of NaOH. What is the pH of the solution at the equivalence point of this titration?
At the equivalence point of the titration, all the weak acid HA has been neutralized by the strong base NaOH. This results in the formation of the conjugate base A-. The pH at the equivalence point of this titration would be determined by the salt formed by the reaction of the weak acid and strong base, and can be calculated using the Henderson-Hasselbalch equation.
Dose a strong base have the lowest pH?
No, a strong base has a high pH, typically above 7. Strong bases dissociate in water to release hydroxide ions, which can increase the pH of a solution. The higher the concentration of hydroxide ions, the higher the pH and the more basic the solution.
When using bases what safety equipment should be used?

How can one determine the acid dissociation constant (Ka) of a substance without using the pH value?
One can determine the acid dissociation constant (Ka) of a substance without using the pH value by conducting a titration experiment. In this experiment, a known concentration of the acid is titrated with a strong base of known concentration. By measuring the volume of base required to neutralize the acid, one can calculate the Ka value using the initial concentrations of the acid and base.
How is salt obtained using the titration method?
an exact volume of the acid is titrated on the base and then placed on a Bunsen burner to be boiled for some time.it can be observed that the salt crystals will be left in the conical flask
What is the pH difference between a strong base and a weak base on the pH scale?
If you are using the common English definitions of "strong" (meaning 'more') and "weak" (meaning 'less'), then a strong base will have a pH of 12-14 while a weak base will have a pH of 7-9. However, there is a specific scientific definition of 'strong' and 'weak' when used to describe acids and bases. In chemistry, a 'strong base' is a base that completely ionizes in water while a 'weak base' is a base that partially ionizes in water. If you are using these definitions, there is no way to categorically compare the pH of a strong base versus the pH of a weak base - the two variables do not related. Some strong (complete ionization) bases will have a lower pH (7-9) while other strong (complete ionization) bases will have a higher pH (12-14); the same is true of weak (partial ionization) bases.
