What indicator in titration of sodium carbonate solution against hydrochloric acid would give a complete neutralization?
The indicator methyl orange can be used in the titration of sodium carbonate solution against hydrochloric acid to give a complete neutralization. At the endpoint, when all the carbonate ions have reacted to form bicarbonate ions, the solution will turn from yellow to pink.
What type of titration is involved in the assay of milk of magnesia?
The assay of milk of magnesia typically involves an acid-base titration. In this process, a known concentration of hydrochloric acid (HCl) is titrated against the magnesium hydroxide present in milk of magnesia. The endpoint of the titration is indicated by a pH indicator, which changes color when the solution reaches neutrality, allowing for the calculation of the magnesium hydroxide content in the sample.
What molecule powers the sodium potassium pump?
The sodium-potassium pump is powered by ATP (adenosine triphosphate). ATP provides the energy needed for the pump to actively transport three sodium ions out of the cell and two potassium ions into the cell against their respective concentration gradients.
Which channel is mainly responsible for the resting potential of a neuron?
The sodium-potassium pump is mainly responsible for establishing and maintaining the resting potential of a neuron. It actively transports sodium ions out of the cell and potassium ions into the cell against their concentration gradients, contributing to the overall negative membrane potential.
What active transport system uses the most ATP?
The sodium-potassium pump, also known as the sodium-potassium ATPase, uses the most ATP during active transport. This pump hydrolyzes one molecule of ATP to move three sodium ions out of the cell and two potassium ions into the cell, against their respective concentration gradients.
Why does a colour change takes place while titrating mohr's salt against potassium dichromate?
From orange to (yellowish) green: It is a powerfull oxidant, used to titrate Fe2+ from Mohr's salt to the oxidised form Fe3+ by the following: Cr2O72−(aq) + 14H+ + 6e− → 2Cr3+(aq) + 7H2O
Which indicator is used while titrating mohrs salt against potassium dichromate using internal indicator analysis?
ferroin indicator
Is methylorange the indicator used in the titration of Na2CO3 against HCl solution?
Methyl orange is not commonly used as an indicator in the titration of Na2CO3 against HCl solution. Phenolphthalein is a suitable indicator for this titration because it changes color in the pH range of the equivalence point.
Is methyl orange the indicator used in the titration of na2co3 against hcl solution?
No, methyl orange is not commonly used as the indicator in the titration of Na2CO3 against HCl solution. Phenolphthalein is the indicator of choice for this titration, as the endpoint is at a pH of around 8.2, which is the color change range of phenolphthalein.
What is nature of titration curve obtained in titration of hcl against naoh?
The titration curve obtained in titration of HCl against NaOH is a typical acid-base titration curve. It shows a gradual increase in pH at the beginning due to the addition of base (NaOH). At the equivalence point, the curve shows a sharp increase in pH since all the HCl has been neutralized. After the equivalence point, the pH continues to rise as excess NaOH is added.
What is the product of titration?
The product of a titration is a titration curve, which is a graph showing the pH or volume of titrant added against the concentration of the analyte in a solution. The shape of the curve can reveal information about the equivalence point, endpoint, and buffering capacity of the solution.
Why potassium permanganate need to be standardized before titration?
Potassium permanganate solutions can lose potency over time due to decomposition, thus requiring standardization to ensure accurate results in titrations. Standardization involves determining the exact concentration of a solution by titrating it against a known standard solution. This allows for the accurate calculation of the concentration of the analyte in subsequent titrations.
What primary standard is used to titrate against potassium hydroxide?
The primary standard commonly used to titrate against potassium hydroxide is potassium hydrogen phthalate (KHP). It is a stable compound with a well-defined molar mass, making it suitable for accurately determining the concentration of a solution of potassium hydroxide.
What are the best indicator use in titration of weak base against strong acid?
The best indicator to use in the titration of a weak base against a strong acid is phenolphthalein. Phenolphthalein changes color from colorless to pink at a pH range of about 8.2 to 10.0, which is suitable for detecting the endpoint of the titration when the weak base is completely neutralized by the strong acid.
What is the Shape of titration curve for complexometric titration?
If we plot the pM (M= concentration of metal ion in the analyte) against the volume of titrant the titration curve takes the sigmoidal shape, plateau in the first part, sharp rise around the equivalence point and then again flat.
What is a white tile and how is it used in titration?
A white tile is a flat, porcelain ceramic plate used in laboratories to provide a contrasting background against colorless solutions during titration. It helps in detecting the color change of the solution being titrated, making it easier to determine the endpoint of the titration accurately.
What is the active transport mechanism by which cells pump sodium and potassium ions against the concentration gradient.?
sodium-potassium pump
