Interpretation:
The balanced net ionic equation for the reaction that takes place when aqueous solutions of the following solutes are mixed should be written. If no reaction is likely, why no reaction would be expected for that combination of solute should be explained.
Concept Introduction:
Deciding which products will form when two or more reactants added together is not an easy task without any experimental evidences. The best way to predict what products will form is to think of various possibilities and then decide which product is most likely to form. A solid compound must have a zero charge.
In a complete ionic equation, all strong electrolytes are represented as ions. But in net ionic equation, only the components which undergo a chemical change are shown. Ions which do not participate directly in the reaction which are called spectator ions are not shown in the net ionic equation.
Answer to Problem 24CR
A net ionic equation is not available.
Explanation of Solution
When potassium nitrate and sodium chloride are mixed, double displacement reaction happens where the two cations of the reactants simply exchange their anions. But no change is visible as all the reactants and products are strong electrolytes, they are completely dissociated in the solution. All ions behave as spectator ions. When we write the complete ionic equation,
All the ions in both sides are cancelled off each other. So there is no net ionic equation.

Answer to Problem 24CR
A net ionic equation is not available.
Explanation of Solution
Both sulfuric acid and nickel (II) sulfate has similar anion SO4 2-. Therefore, even though they exchange their anions, a chemical change will not happen. So this reaction is not likely to happen. The complete ionic equation is,
All the cations and anions cancel off each other so no net ionic equation is available.

Ru-2 is weakly luminescent due to the effective photoinduced electron transfer (PET) from Ru(II) luminophore to electron acceptor, 2,4-dinitrobenzene-sulfonyl (DNBS). In the presence of biothiols, such as glutathione (GSH), cysteine (Cys), and homocysteine (Hcy), the emission of Ru-2 solution was switched ON, as a result of the cleavage of quencher to form the product, Ru-1. Ru-2 showed high selectivity and sensitivity for the detection of biothiols under physiological conditions, with detection limits of 62 nM, 146 nM, and 115 nM for GSH, Cys, and Hcy, respectively. The emission lifetimes of Ru-1 and Ru-2 were measured to be 405 and 474 ns,…arrow_forward
- In an effort to reduce costs and increase the accessibility of instruments that utilize spectrophotometric detection, some researchers are beginning to experiment with 3D-printed parts. One example of this is the 3D-printed flow cell, shown at right. This device was made using polylactic acid and accommodates a LED at one end and a detector at the other. It can be used for standalone flow injection spectrophotometry or coupled to a chromatographic separation to be used as a detector. Explain why the sensitivity varies with the length of the flow cell, as shown in the data below. Could this setup be used for fluorescence analysis? Why or why not?arrow_forwardThe dark lines in the solar spectrum were discovered by Wollaston and cataloged by Fraunhofer in the early days of the 19th century. Some years later, Kirchhoff explained the appearance of the dark lines: the sun was acting as a continuum light source and metals in the ground state in its atmosphere were absorbing characteristic narrow regions of the spectrum. This discovery eventually spawned atomic absorption spectrometry, which became a routine technique for chemical analysis in the mid-20th century. Laboratory-based atomic absorption spectrometers differ from the original observation of the Fraunhofer lines because they have always employed a separate light source and atomizer. This article describes a novel atomic absorption device that employs a single source, the tungsten coil, as both the generator of continuum radiation and the atomizer of the analytes. A 25-μL aliquot of sample is placed on the tungsten filament removed from a commercially available 150-W light bulb. The…arrow_forwardDon't used hand raiting and don't used Ai solutionarrow_forward
