Is caesium soluble in water?
The cesium will react with the water and create an explosion. This is due to the fact that it is in the Alkali metals column, which all react with water. The reaction strength increases the further down the column you go Caesium (cesium in USA) metal reacts rapidly with water to form a colourless solution of caesium hydroxide (CsOH) and hydrogen gas (H2). The resulting solution is basic because of the dissolved hydroxide. The reaction is very exothermic. The reaction is so fast that if the reaction is carried out in a glass vessel, the glass container will shatter. Although not known for certain, the reaction is probably slower than that of francium (immediately below caesium in the periodic table). The reaction is faster than that of rubidium (immediately above caesium in the periodic table). 2Cs(s) + 2H2O → 2CsOH(aq) + H2(g) it blows up
What is the difference between ammonia clock and caesium clock?
Both are atomic clocks but caesium atomic clock is more accurate as the internal frequency of caesium atom is more accurate and varies less than one part in 10 billion.
Is cesium soluble?
YES!!! It is very soluble to the point of explosiveness. If you place a pellet of caesium in water, it will dissolve, releasing hydrogen in the process. Because it is also an exothermic reaction the hydrogen will ignite with oxygen(air) , with a bang and flame flash. The reaction equation is 2Cs(s) + 2H2O(l) = 2CsOH(aq) + H2(g) The H2(g) will then ignite in the air because of the heat of the reaction and form water. 2H2(g) + O2(g) = 2H2O(l) Caesium is a Group (I) metallic element, and reacts in a parallel sense to the other Group(I) elements. NB Frencium (Fr) is also a Group(I) element , but not found in the open lab. because it is radio-active.
Is caesium chloride a metal?
Caesium chloride is a salt.
What is the odor of caesium?
Californium has no odor.
What names and formulae of the two products of the reaction between caesium and water?
2 Cs + 2 H2O → 2 CsOH + H2 caesium+water = caesium hydroxide+hydrogen
Why cant other alkali metals be substituted?
Alkali metal atoms can often be substituted by other atoms under the right conditions An example is Caesium in Caesium Chloride. By heating Caesium chloride with Calcium metal, caesium is substituted by calcium and the caesium can be distilled off at about 700oC under vacuum. This seems surprising, particularly given the higher reactivity of caesium, but the greater lattice energy of calcium chloride makes this the energetically preferred product over caesium chloride and drives the reaction. (As an aside, this was the most terrifying reaction that I ever did in a lab because of the high temperature caesium that is produced...)

What chemical properties would you expect caesium to have?
Caesium is freshly cut, it have a metallic shine, but this disappears rapidly due to reaction of exposed metal surface with oxygen in the air
Balanced equation of reaction of caesium with iodine?
2Cs (s) + I2 (l) = 2CsI (s)
If universal indicator was added to the water after the reaction with caesium what colour would it go and why?
Caesium recats with water to form caesium hydroxide , a base. the universal indicator woulg change color to be brown/purple depending on the concentration i.e pH. see link
What is the symbol equation for caesium reacting with water?
the formula for water is simply H2O (two hydrogens, one oxygen). The formula for cesium is Cs, it is a simple element. If you mean the reaction equation it is 2Cs + 2H2O --> 2CsOH + H2 The products are cesium hydroxide and hydrogen gas.
What metals can react explosively with cold water?
Rubidium, caesium and francium. Potassium will generate enough heat to ignite the hydrogen produced in the reaction but the reaction is not really explosive.
Would caesium with water be more reactive thank the reaction of sodium with water?
Yes, I saw a demonstration of this on a video once...

What is the word equation for caesium reacting with water?
Caesium + water ------> Caesium hydroxide + Hydrogen
