### How concentrated does the analyte solution need to be in order to perform a (chelatometric) titration

I’m currently investigating a method to chemically pretreat cellulosic waste as bisorbents for enhanced uptake of lead in water. I intend to measure the initial and final concentration of water to ...

### How does changing the concentration of the titrant affect the pH at the equivalence point? [closed]

For example, if we doubled the concentration of a strong acid titrant, would the pH at equivalence point then decrease because the equivalence point volume has decreased too - since pH is dependent on ...

### What is the difference between Half Equivalence point and Equivalence point?

OKay I learned in class that equivalence point is the time of neutralization, where the # of moles of acids and base present is in equivalence/same amount. Now I was also told that Half equivalence ...

### Why does a strong base completely neutralize a weak acid? [closed]

For the longest time, weak acid-strong base titration curves completely baffled me. I understood that the equivalence point of a strong acid-strong base titration is reached when equal numbers of ...

### How do you find the ph of lime juice through titration?

I am doing an experiment on the effect of time on the pH of Lime juice. I was wondering how you would calculate the pH through titrations using 1 Molar NaOH. I have been racking my brain on this for a ...

### Why does the concentration of the acid equals that of the base at the mid-point of titration? [closed]

Consider this graph of the titration of a weak acid and a strong base: The buffering region is strongest at the midpoint of titration because there is equal concentrations of acetic acid and its ...

### Measure ethanol volume fraction in a beverage [closed]

Given a sample of an alcoholic beverage (be it beer, wine, etc..), what are possible methods to find out the ABV (alcohol by volume) of it with moderate accuracy? As fas as I know, some methods exist ...

### Why is high molar molar mass a requirement of good primary standards for volumetric analysis? [closed]

I have been taught that using primary standards with a relatively high molar mass will reduce the error between the equivalence point and the end point during titration. However, I am unsure as to why ...

### What is the relation between volume strength and normality of H2O2? [closed]

I have been told that: $$\text{equivalent weight of }\ce{H2O2} =\text{molecular weight of } \ce{H2O2}$$ as it's $n$-factor is $1$ (from balanced equation). But in my book it's given that: ...
