Water with sodium

Reaction of sodium with water. When a very small piece of sodium is added to water, it reacts violently with the water. The OH- ions formed in the reaction turn the acid-base indicator phenolphthalein from colorless to pink. 

Now we come to an important interpretation of a chemical equation. First, we note that the equation for the reaction of sodium with water tells us that... 

Compounds containing the functional group —OH are called alcohols. The —OH group is covalently bonded to a carbon atom in an alcohol molecule, and the molecules do not ionize in water solution to give OH ions. On the contrary, they react with metallic sodium to liberate hydrogen in a reaction analogous to that of sodium with water. 

Except for being much less vigorous, this reaction is analogous to the reaction of sodium with water,... 

The collected papers of a symposium at Dallas, April 1956, cover all aspects of the handling, use and hazards of lithium, sodium, potassium, their alloys, oxides and hydrides, in 19 chapters [1], Interaction of all 5 alkali metals with water under various circumstances has been discussed comparatively [2], In a monograph covering properties, preparation, handling and applications of the enhanced reactivity of metals dispersed finely in hydrocarbon diluents, the hazardous nature of potassium dispersions, and especially of rubidium and caesium dispersions is stressed [3], Alkaline-earth metal dispersions are of relatively low hazard. Safety practices for small-scale storage, handling, heating and reactions of lithium potassium and sodium with water are reviewed [4],... 

Exercise 2-5 Write balanced equations for the reactions of (a) metallic sodium with water, (b) metallic sodium with methanol, (c) sodium hydride with water, and (d) sodium hydride with ethanol. 

A concrete example is the reaction of solid sodium with water which results in a solution of sodium hydroxide and hydrogen gas ... 

Reactive metals such as potassium, sodium and calcium react with cold water to produce the metal hydroxide and hydrogen gas. For example, the reaction of sodium with water produces sodium hydroxide and hydrogen. 

Fresh material behaves like sodium with water, hissing, forming a diminishing floating globule, and often finally exploding [1]. Old, degraded (yellow) samples... 

Hydrolysis and more particularly deuteriolysis of the M14—Mi or M2 bond is one of the best ways to characterize M14 anions, mainly used in germanium, tin and lead chemistry3 4 8 (equations 75 and 76)20,86. This characterization reaction becomes very typical in the case of hydrometal-14 anions from the coupling constant between hydrogen and deuterium observed in 111 NMR spectra (equation 77)16.29 30. The reaction of plumbyllithium or sodium with water was reported to be more complicated and lead to PbO8. 

Hydrogen may be displaced from water by a very active metal. Alkali metals are particularly reactive with water, and the reaction of sodium with water often is exothermic enough to ignite the hydrogen gas released. 

In room 410 a fire was caused by the reaction of chemicals in a similar manner (the reaction of sodium with water as described in reference 3 5 5 ), but it was extinguished by students in attendance. The students, after closing the windows and doors of the room, went out to help fight the fire in room 403. 

This law is based on the fact that the products and the reactants of a reaction are made up of the same number and kinds of atoms. The atoms are just rearranged and connected differently. Look at the formula equation for the reaction of sodium with water. 

During diarrhea, the small intestine retains its ability to actively transport monosaccharides such as glucose. Glucose actively carries sodium with water and other electrolytes. Because the WHO-ORS has a high sodium concentration, U.S. physicians have been reluctant to use it in well-nourished children. Yet controlled comparative studies describe more favorable results with the WHO-ORS than with parenteral fluids. Amino acids promote sodium transport and act as... 

Reaction (5.91) occurs in an acid solution, whereas + O2 (reaction 5.96) proceeds in neutral and alkaline solutions. Interestingly, the above discussed reaction of elemental sodium with water is now considered a source of hydrated electrons (Hughes and Lobb 1976) ... 

FIGURE 8.9 A favorable exergonic reaction. The favorable driving forces combine to make the reaction of sodium with water dramatically exergonic. 

The possibility of reaction of the coolant (sodium) with water and air (fire). 

Constract a table with the headings q, w, AE, and AH. For each of the following processes, deduce whether each of the quantities listed is positive (+), negative (—), or zero (0). (a) Freezing of benzene, (b) Compression of an ideal gas at constant temperature. (c) Reaction of sodium with water, (d) Boiling... 

Figure 8.15 Reaction of sodium with water. A single-replacement reaction occurs when sodium, an element, reacts with water, a compound. The metal sodium appears to replace hydrogen in water, 2 Na + 2 HOH (A + BX) 2 NaOH + Hj (AX + B). The...
