Types of conductometric titration?
Some types of conductometric titrations include acid-base titrations, redox titrations, and precipitation titrations. Conductometric titration involves measuring the change in electrical conductivity as reactants are titrated against each other until an equivalence point is reached.
Indicators used in acid base titration?
It depends on the acid or base used. For strong acid vs. strong base, phenolphthalein can be used as indicator. For strong acid vs. weak base, methyl orange can be used as indicator. For weak acid vs. strong base, phenolphthalein can be used as indicator.
Why must use buffer solution in titration involving EDTA?
EDTA is Ethydiaminotetraacetic acid. In some titrations, it is best to avoid any sharp pH changes(except in acid-base titrations, of course). Buffers are the right substances to help maintain a constant pH.
What is the General equation for acid reacting with a base?
acid + base → salt + water
What is left when a base and an acid neutralize?
A salt and water. For example if you add hydrochloric acid to sodium hydroxide (a base), you will get sodium chloride (a salt) and water. ie. HCl + NaOH -> NaCl + H2O But unless the acid and base are perfectly balanced you'll have some acid or base left over.

Why is the base added to the acid and not the other way round?
Bases are typically stronger than acids, so adding acid to base ensures that the reaction is not too vigorous. Additionally, some reactions involving bases generate a lot of heat, so adding acid onto the base allows for better control of the reaction temperature.
How are acid salts different from other salts?
Salts are the result of acids neutralizing bases. If the base is weak and the acid is strong, the salt will have some acid character. If you dissolve an acid salt in water, it will lower the pH.
When copper reacts with oxygen is the acid formed a acid or a base?
Cuprous and cupric oxide are base forming oxides, only nonmetals can have acidic oxides, though some other metal (amphoteric) oxides are also (mainly weak) acid forming oxides.
At what point in a titration are the amounts of hydronium ions and hydroxide ions equal?
This is at the 'neutral' point, when pH is exactly 7.0 (at room temperature). This is NOT necessarely the same pH as at equivalence point, the latter can be (somewhat) higher or lower than 7, depending on the substance to be titrated, in acidimetric titrations that is. (Some oxidimetric or other kind of volumetric titrations the pH can be very different and not changing anyhow).
Why doesn't borax and vinegar react?
Borax and vinegar do not react because they are not reactive with each other in the same way that some other acid-base or redox reactions occur. Borax is a weak base, while vinegar (acetic acid) is a weak acid, and they do not have the necessary components to undergo a chemical reaction when combined.
What are some dangerous chemical reactions?
acid and a base
Why are titrations useful?
As you are using different indicators and you will be knowing either the acid's or base's pH,so it helps in understanding the science behind the pH.As you can find now,whether your area water has some stagnate water mixed with it or not could be determined by you,Instead of going to any government labs or technologies.It is something practical and the other is it is the basic and important step to start chemistry.
