Is one method for detecting the endpoint of a titration involves using an idicator dye that changes color at different pH values true or false?
True. One method for detecting the endpoint of a titration is indeed using an indicator dye that changes color at different pH values. The color change of the indicator dye can be observed to determine when the reaction between the titrant and analyte is complete.
What is the chemical formula for lithium arsenide?
Li3As since lithium has a charge of +1 and arsenic has a charge of -3, you do the crossing method and it becomes Li3As
What elements has four valence electrons shows properties of metals and nonmetals and has 14 protons in the nucleus of each atom?
Arsenic is atomic number 33 and has 5 valence electrons. Method for finding valence electrons: All electrons are arranged in orbital shells. The inner shell can hold up to 2 electrons. The second shell holds up to 8. The third shell holds up to 18 and so on. The outer shell holds the valence electrons. To find out how many there are, count the electrons in the inner shells 2+8+18 = 28, in this case, and subtract them from the 33 electrons that Arsenic has: 33 - 28 = 5 valence electrons.
How do you test a compound?
ELISA(enzyme-linked immunosorbent assay) is a useful method for detecting the concentration of some compound, using the characteristic of specific binding between antigen-antibody. For macromolecular compounds,you can use SandwichELISA.To small molecule compounds,Competitive ELISA is suitable.Meretciel offer ELISA kits.
Is there a method for detecting starch without using iodine?
if you put iodine in food and it contains starch it should change color.
What is the most common method of poisoning?
The most common method of poisoning is arsenic, because it is water soluble and tasteless.
What do you use to find plate boundaries?
Linear patterns of earthquakes is one method of detecting them.
How can CSIs use the method fro detecting who wrote a suspicious note?
Staring it down and beaing board
Is the detection of neutrons dependent on the energy of the neutrons?
Yes. There are different kinds of detectors for neutrons. Some are better at detecting high energy neutrons, and some are better at detecting thermal neutrons. There is no detection method that is equally good for detecting neutrons at all energy levels.
Ndt methods of detecting welding defects?
The best method for detecting defects in welds is Magnetic Particle. You can also use Fluorescent penatrent, and x-ray but they can be time consuming and often unreliable.
What are sonar rays?
Sonar is a method of detecting underwater objects with sound pulses-like radar but with sound not microwaves
