What are the types of standard solutions?
The two main types of standard solutions are primary standard solutions, which are highly pure and stable substances that can be used to make precise titrations, and secondary standard solutions, which are solutions prepared using a primary standard solution as a reference for their concentration.
Why is it necessary to standardize a solution of NaOH using a primary standard, such as KHP?
It is necessary to standardize a solution of NaOH using a primary standard like KHP because primary standards are highly pure and have a known exact mass. This allows for accurate and precise determination of the concentration of the NaOH solution, ensuring reliable and consistent results in experiments.
How do we determine molar extinction coefficient using standard plots?
In the beginning, no you need not cull the special coefficient
Why primary and secondary standard solutions are needed in analysis.?
Primary standards have some peculiar propertiesThey are nonsensitive to atmospheric oxygenThey have known formula and molecular weightThey are usually high molecular weight compoundsThey have a constant concentration /uniform composition for a long period of timeThey are powerful reactantsSecondary standards areInfluenced by atmosphere/environmentConcentration change over timeUsually powerful reactantsUsually cheap & easy to useZeryawkal Ergetie(Msc in pharmaceutical Analysis )
The use of a triple-beam balance to determine the mass of a rock is an example of measuring by using?

How to prepare a standard solution of potassium iodate?
To prepare a standard solution of potassium iodate, you would need to weigh out a known quantity of potassium iodate, dissolve it in a known volume of water, and make up the solution to a specific volume using a volumetric flask. This process allows you to accurately determine the concentration of the solution.
What is a sentence using the word vegetable?
The patient suffered a traumatic head injury and it was determined he would be a vegetable for the rest of his life. My favorate vegetable is the potato.
How much does a vegetable stock weigh i grams?
The weight of vegetable stock can vary based on the specific ingredients and water content, but on average, 1 liter of vegetable stock weighs approximately 1,000 grams (or 1 kilogram). If you are using a standard recipe, the weight may fluctuate slightly depending on the concentration and the specific vegetables used. For precise measurements, it's best to weigh the stock after preparation.
How can you determine someone's height from a picture?
One way to determine someone's height from a picture is by using a known object of a standard size in the photo, such as a door frame or a ruler. By comparing the size of the object to the person in the picture, you can estimate their height.
Is the US using the gold standard for 2010?
No, they stopped using the gold standard in 1971
What are McFarland's standard opacity tubes?
a set of reference tube used to determine the number of bacteria of a suspension using the principle of difference in turbidity with change in cell number
What is the definition of fruit and vegetable carving?
