according to the Mathiessan's rule, the overalll temp dependant mobility is determined by the lattice vibration (phonon) scattering limited mobility (µL)and scattering by impurities( µI)... as 1/µ=1/µL+ 1/µI....... the lowest value among these two determines the overall mobility... so if the value of µL is low, it means the metal is pure...

How do you find purity of Ferric and non Ferric alum?
The purity of Ferric and Non-Ferric alum can be determined by conducting a chemical analysis to measure the percentage of the specific compound in the sample. This can be done using techniques such as titration, spectroscopy, or chromatography to quantitatively determine the purity of the sample. It is important to compare the results obtained from the analysis with the known standards to assess the purity accurately.
How do you measure purity of gold?
The purity of gold is measured in karats or fineness. Karats range from 1 to 24, with 24 karat gold being the purest. Fineness is expressed as a percentage, with 100% being equivalent to 24 karats. Gold purity can be determined by using testing kits, electronic testers, or by sending samples to a professional assayer.
What is Purity testing procedures for HCl?
The purity of hydrochloric acid (HCl) is typically tested by measuring its concentration using techniques like titration or spectroscopy. Impurities such as metal ions, organic compounds, or other acids can also be tested for using methods like atomic absorption spectroscopy or gas chromatography. Additionally, physical properties like density or refractive index can provide clues about the purity of HCl.
Does anyone have a GC purity method for chloroform?
Yes, a common method for assessing the purity of chloroform using gas chromatography involves injecting a sample into a GC system equipped with a flame ionization detector. The purity is typically determined by comparing the peak area of the chloroform to the total peak area of all components in the sample. It's important to have a well-characterized standard to quantify chloroform content accurately.
A sentence using the word determined?
I am determined not to answer your question.
How do you determine the purity of caustic soda?
The purity of caustic soda (sodium hydroxide) can be determined through a titration method, typically using a standard acid, such as hydrochloric acid. A known concentration of acid is added to a solution of caustic soda until the reaction reaches the endpoint, indicated by a pH indicator or pH meter. By calculating the amount of acid used to neutralize the caustic soda, the concentration of sodium hydroxide can be determined, allowing for the calculation of its purity. Additionally, methods like spectroscopy or gravimetric analysis can also be employed for more precise measurements.
What is peak purity?
Peak purity refers to the assessment of the quality and specificity of a chromatographic peak, indicating how free it is from impurities or overlapping signals. It is typically determined by evaluating the spectral data of the peak, often using techniques like UV-Vis or mass spectrometry. A high peak purity suggests that the peak represents a single compound, whereas lower purity indicates potential contamination or co-elution with other substances. This assessment is crucial in analytical chemistry for ensuring the accuracy and reliability of quantitative results.
How do you determine heavy metal using UV spectrophotometer?
Heavy metals can be determined using a UV spectrophotometer by first preparing a sample solution containing the heavy metal ions. The presence of the heavy metal ions will cause a characteristic absorption spectrum in the UV range. By measuring the absorbance of the sample solution at specific wavelengths and comparing it to a standard curve or known values, the concentration of the heavy metal ions can be determined. Specialized techniques like chelation and complexation may be used to enhance the sensitivity and selectivity of the method.
How purity of compound is check?
The purity of a compound can be checked using various analytical techniques such as chromatography, spectroscopy, or titration. These methods can determine the amount of impurities present in the compound and provide a percentage of purity based on the results obtained. It is important to use a combination of techniques to confirm the purity of a compound accurately.
What is used to identify the purity of a substance?
The purity of any substance can be checked through Melting Point,Boiling Point or Chromatography. As A pure substance has a set and exact melting point and boiling point and a pure substance shows only one spot on the chromatogram.
How can you determine the purity of amino acid using paper chromatography?
To determine the purity of an amino acid using paper chromatography, you would first need to separate the amino acids using paper chromatography. Once the amino acids are separated on the paper, you can calculate the Rf value (retention factor) for each amino acid. Comparing the Rf values of the sample amino acid to a standard of known purity can help determine the purity of the sample.
How can I ensure the purity of distilled water when using an autoclave for sterilization processes?
To ensure the purity of distilled water when using an autoclave for sterilization, it is important to regularly check and maintain the autoclave equipment to prevent contamination. Additionally, using high-quality distilled water and following proper sterilization procedures can help maintain the purity of the water during the sterilization process.
