XRD Full Form In Chemistry? How to Explain XRD Results ?

XRD Full Form In Chemistry

The XRD full form in chemistry is X-ray powder diffraction

• It is a laboratory-based analytical method primarily used for phase identification of crystalline material.
• XRD diffraction is often used to compare base catalyst and their modification to see if the crystal structure is retained and how much crystanality the catalyst after the modification has gained or lost 
• For example, XRD graph shown below contains parent catalyst HZSM5 is compared with Si modified ZSM5 (Si/HZSM-5), Zn modified Si/HZSM-5 catalysts (1 wt% ZnSi/HZSM-5, 1.5 wt% ZSM-5) and 1wt% Zn/HZSM-5.

XRD patterns

How to explain XRD results

One can explain XRD analysis from the figure given above in the following way 

• The figure shows the XRD patterns of the catalysts. From the figure, it can be seen that the parent catalyst HZSM-5 exhibit characteristic peak between 5-10°and 21-25°.
• The XRD peaks for the Si-modified, Zn-Si modified and Zn modified HZSM5 respectively are very similar to those of HZSM-5. 
• No new diffraction peak is observed on the modified catalysts compared to that of HZSM5 catalyst which suggests that the MFI structure of the HZSM-5 catalyst was intact. 
• No characteristic peak of ZnO at 2θ = 31.6°, 36.1° were observed on Zn-Si modified catalysts and Zn modified HZSM5 suggesting that Zn species were highly dispersed on parent and Si/HZSM5 catalysts respectively     

I hope this article helped you to know the XRD full form and how to explain XRD results

• The name .com is originally derived from the word commercial and the domain is registered by a commercial organization. 
• .com is generally used to categorize websites especially commercial websites
• Over the years it has grown into the largest top-level domain

History of .com

• It was first added on 1 January 1985
• United Defence Department of Defense originally administered the domain, but today it is operated by Verisign under the jurisdiction of United States law 
• The first .com was claimed by a computer manufacturer called Symbolics, Inc

EBT Full Form in Chemistry | EBT Indicator Full Form

 EBT Full Form in Chemistry

The EBT full form in chemistry (EBT indicator full form) is Eriochrome Black T. 

• The EBT is an azo dye and has functional group  R−N=N−R′, in which R and R′ are usually aryl. The EBT indicator structure is shown below. 

Structure of EBT Indicator (Eriochrome Black T)

• It is a complexometric indicator used in complexometric titrations 
• It is known for its chelating properties 
• The Eriochrome is a trademark of am American company Huntsman Petrochemicals, LCC 

Applications of EBT in chemistry

• It is mainly used as an indicator to determine the hardness of the water in the EDTA method
• In complexometric titrations, the compound is used as an indicator, as an acid-base indicator. The indicator forms complex with metals ions like Ca2+, Mg2+ etc
• The indicator is used to determine the concentration of Ca2+ using the complexometric method 

Eriochrome Black T colour change

• The colour of Erichrome Black T is blue in its deprotonated form but when it forms a complex with metal ions like calcium magnesium or other metal ions the colour changes from blue to red. For example, see in the figure below, the EBT is blue in a buffered solution at pH 10 but it turns red when Ca2+ ions are added.

Aq Full Form in Chemistry | What does Aq mean in Chemistry ?

Aq Full Form in Chemistry

What does aq mean?

The aq full form in chemistry is an aqueous solution. The aq is mostly shown in chemical equations and appear in the description of the research papers 

What does aqueous mean in chemistry

• The word aqueous comes from aqua and the meaning of aqueous is water. 

Aqueous solution meaning 

• A solution in which water is used as a solvent (dissolving medium) to dissolve other chemical substances (solute) is called an aqueous solution.
• The hydrophilic substances (water-friendly) dissolves in water easily. Examples of acids, bases and salts  are hydrophilic

Examples of aqueous solution are 

• An aqueous mixture of Sodium chloride in water 

          NaCl(s) → Na+(aq) + Cl-(aq)

• Sodium hydroxide dissolved in water 

Types of aqueous solutions (aq solutions)

There are two types of aqueous solutions

• Electrolyte solutions 

              They contain dissolved ions and can conduct electricity 

               Eg.  Sodium chloride in water, NaCl dissolves in water and dissociates to form ions

• Non-electrolyte solutions

             They do not contain ions in the solution, therefore, they do not conduct electricity 

              Eg. Glucose (Sugar) dissolved in water, glucose dissolves in water but does not dissociate into ions in the solution. At the molecular level sugar structure remains intact 

Non-aqueous solution meaning

• A solution in which liquid is used as a solvent except water to dissolve other chemical substances (solute) is called a non-aqueous solution 
• Non- aqueous solvents are alcohols, ethers, benzene, acetone, toluene, vegetable oil etc

Non-aqueous solution examples 

• Sulphur (solute)  dissolved in carbon disulphide(solvent or dissolving medium) 
• Iodine dissolved in alcohol, 
• Iodine dissolved in CCL4
• Benzene dissolved in toluene

NTP Full Form and STP Full Form in Chemistry

As the temperature and pressure vary at different places, a standard reference is needed for comparing the testing and the documentation of chemical processes and physical process. The NTP and STP respectively are used to define conditions. What is NTP full form and STP full in chemistry respectively is given below

NTP full form in chemistry

The NTP full form is Normal Temperature and Pressure defined by the National Institute of Standards and Technology (NIST). The NTP is widely used as a practical standard by Industries through the world because NTP conditions are more realistic and convenient condition.

• In NTP the normal temperature is 20-degree Celsius or 293.15 K or 68-degree F. This temperature is convenient to use as compared to 0-degree Celcius. 
• In NTP the normal pressure is 1 atm or 101.325 kpa or 760 mmHg (or torr) or 14.6959 psi
• One mole of an ideal gas occupies 24.0 litres (dm3)  of volume at NTP condition

STP full form in chemistry

The Full form of STP is Standard Temperature and Pressure defined by NIST. it is commonly used to state standard conditions for temperature and pressure.

• In STP the standard temperature is  0º C or 273 K) or 32 F
• The standard pressure is 1 atm or 760 mmHg
• 1 mole of an ideal gas occupies 22.4 litres (dm3) of volume at STP condition
