What kind of indicators are used in precipitation titration?
An example of an indicator would be Phenol Red, or Universal Indicator. Depending on the pH range of the indicator and the pH range of the substrates you would use the appropriate indicator.
How do you find the pH of a solution using a universal indicator?
pH indicators are usually weak acids or weak bases that change their color depending on their dissociation (protonation) state. Sometimes both forms are colored, sometimes only one. In most cases you may assume that to completely change color of bicolored indicator pH must change by 2 units. However, human eye is more sensitive to some colors than to others, thus some color changes can be perceived over wider pH range. pH indicators can be used to check pH of the solution, although they are rarely added directly. Only in acid-base titrations indicator should be added to the solution. To check pH it is much more convenient to use pH strips. It is worth of noting here that pH strips are nothing else but pieces of paper impregnated with indicator or a mixture of indicators.
What is litmus solution?
yes it is
How do oxalic acid and sulfuric acid differ during titration?
Sulfuric acid has hydrophilic properties when concentrated, so it may have some effect on the reaction taking place. Oxalic acid is an reducing agent, so in titrations - which usually involve some kind of redox - it may begin reacting in ways not intended.
What do mean by dichromatometry?
Dichromatometry is a kind of titration used in analytical chemistry, where Potassium Dichromate (K2Cr2O7), a primary standard substance solution is used for estimation of mainly metal ions, like Fe+2 etc. As dichromate is used as the titrating substance, the name dichromatometry. Mainly BDS (Barium Diphenylamine Sulphonate) indicator is used in this kind of titration.
Why and when phenolphthalein used as the indicator?
There are a lot of indicators around. Choosing which one to use depends on what you're analyzing for, what pH the endpoint happens at, what kind of reaction is happening in the flask, etc. Some common ones are Methyl Orange, Methyl Red, Starch, Bromphenol Blue; the list goes on.

What kind of rocks have diamonds?
Indicator minerals for diamond include kimberlite and lamproite.
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).
What is calculated by dividing the number of one kind of possible outcome by the total number of all possible outcomes?
The probability of that one special kind of outcome.
