5 ml of 0.75 M NaOH was added to a beaker, followed by methyl orange and then HCl dropwise until the transition point was reached, which was 3.75 ml of HCl consumed. How would the transition point change if the sample volume were halved?

Loading...I have a question about task 3. Why does the concentration of acetate ions increase when salt is added to the acid? I don't understand. reaction equation Ch3COOh + CH3COONa –> Ch3COOH + NaOH?
My father sprayed oil on my window today because it was squeaking, and I'm sleeping in that room now. Is it harmful to inhale the oil?
Tea and non-alcoholic beer are nothing more than water with plant extracts. Chemically speaking, it's the same thing, right?
Hello, I was wondering if someone could take a look at this and see if it's correct? I would be very grateful 🙂
The solubilities of LiF and KF are 2.7 g/L and 485 g/L, respectively. The solubilities of MgF 2 and MgBr 2 are 0.13 g/L and 1015 g/L, respectively. Explain the different solubilities of the pairs using the HSAB concept.
I have a few questions regarding complex metric titration… How can one determine which form of EDTA (H 4 Y , H3Y- etc.) reacts with metal ion? Below which pH value can the titration of metal ions with EDTA be carried out? So how does pH affect the number of protons that are free in…
Now consider exactly what influence the volume has in GLEICHBLEIBENDER concentration.
You will need less HCl with the same concentration for neutralization, but both are strong acids and bases. What would change at best at the envelope?
At 1.875 ml of HCl consumption?
That’s right. The amount of HCl that you need to reach the envelope would halve. only 1.875 ml of HCl are required.
> How would change the transition point
It is not changed (same color change at the same pH value), it is only somewhere else (with less addition) … (at least if the indicator quantity is halved). The “how” is too non-specific.
The envelope depends ONLY on the chemical properties and concentration of the indicator and NOT on the sample quantity in the solution. The transition point of methylorange is 3.1 to 4.4. That remains. So the envelope would not change if you halve the sample amount.
