The reaction of zinc nitrate and excess sodium hydroxide begins with precipitation of zinc hydroxide ( Zn(OH)2 ), followed by dissolvement after adding excess sodium hydroxide ( 2 OH- ) to formation of zinc aat-ions ( [Zn(OH)4]2- )
Zinc hydroxide precipitates while sodium nitrate remains in solution.
well when a kid brings a gun to school and starts shooting your reaction time will have an effect on your survival chances
It depends on the original temperature, but the rule of thumb is that near normal room temperature, raising the temperature by ten degrees will roughly double the reaction rate.
Under deep anesthesia the respiratory reaction to CO2 disappears but in response to reflex stimulation remains the same as under moderate anesthesia .
It depends on the molecule of course. some molecules have a soft hydroxide group, that is a OH sticking out somewhere that isn't all that closely held. Increasing the pH in the environment of such a molecule can result in a free hydrogen ion latching onto the hydroxide group and forming a water molecule - in effect removing the hydroxide group from the molecule. This is a process known as dehydration - the removal of water. Dehydration is both an important and detrimental process in making Urea, a nitrogen rich fertilizer. Some slightly complex molecules we 'bend into a new shape' in the presence/absence of hydrogen ion. The electro-presence of hydrogen ions affecting the arrangement of certain hydrogen bonds with in the molecule. This is the case with some pH indicators. This bending and refolding can occur countless times as there is no net change to the molecule.
Typically heat will speed up a chemical reaction because it causes the actual atoms to move quicker and collide with each other causing a chemical reaction. For example a redox reaction where a electron is passed between atoms.
There is no reaction , because of the Common Ion Effect. The Common Ion is the Hydroxide.
The effect of a Cannizzaro reaction involves the attack of hydroxide. This results in an attack on another molecule, which results in the exchange of a proton.
Product depends on reaction conditions and quantity of sodium hydroxide used in the reaction. Initially sticky product [sodium salt of methyl salicylate] will form that on heating will effect saponification [hydrolysis of ester] resulting in sodium salicyale.
The dark spots on a mirror are the effect of the decomposition of silver nitrate (AgNO3) to silver (Ag).
the solution will turn into pink(which will gradually fade afterwards because carbon dioxide is present in the air that neutralizes the color effect of the hydroxide..
A litmus test is one way of comparing. Sodium Chloride is a neutral salt and so would have no effect on litmus. Sodium Hydroxide is a base, and would turn litmus blue.
Sodium hydroxide would do. NaOH + HCl -> NaCl + H2O Neutralization reaction producing salt ( common table salt ) and water.
Bleach consists of chlorine gas dissolved in an alkali-solution, such as sodium hydroxide (NaOH). When chlorine is dissolved in an alkalic solution, hypochlorite ions (OCl-) are formed during an autoredox reaction. Chlorine reacts with sodium hydroxide to sodium hypochlorite (NaOCl). This is a good disinfectant with a stable effect.
Its bad, mkay
Instant cold packs use water and ammonium nitrate. The ammonium nitrate is a powder found inside the cold pack, and the water is inside a plastic container inside the cold pack. When the plastic container containing the water is broken and mixed with the ammonium nitrate, the water dissolves the ammonium nitrate, which is overall an endothermic reaction, causing the cold pack to get cold.
adverse reactions are always unintended and harmful even on a correct dosage while side effects are always predicted and can be desirable or undesirable even on a correct dosage.
it decomposes into potassium nitrite and oxygen.
