When hydrochloric acid neutralizes sodium hydroxide the temperature increases is this exothermic or endothermic?
When the temperature increases as a result of reaction, as specified here, the reaction is exothermic.
Is obtaining lime from limestone exothermic?
The hydratation of concentrated OH- and Na+ ions (by dilution) is exothermic, it gives an energetically prefered state of matter.(Hydratation is the extra surrounding of the ions by polar water molecules of the solvent).
When solid sodium hydroxide is added to water the solution gets hot is this endothermic or exothermic?
The hotness of water proves heat is absorbed by water so the process is exothermic which releases the heat and is absorbed by water.
Why some reactions are endothermic or exothermic?
Put in a simple way, endothermic is when the chemical reaction "absorb" heat or the temperature of the mixture increases. On the other hand, exothermic is when the chemical reaction "free" heat and the temperature of the mixture decreases.
Do acids create hydroxide ions when dissolved in water?
No, acids do not create hydroxide (OH-) ions when dissolved in water. Acids create Hydrogen (H+) ions when dissolved in water.Bases create hydroxide ions when dissolved in water.

Endothermic
Is barium hydroxide endothermic or exothermic?
it is exothermic since it produces energy. if endothermic it would use up energy.

Take about 2 g barium hydroxide in a test tube. Add 1 g of ammonium chloride and mix with the help of a glass rod. Is this an exothermic or an endothermic reaction?
it is an endothermic reaction in which heat is absorbed.
Is the dissolution of calcium hydroxide exothermic or endothermic?
Exothermic: Heat is given off as one of the products. The container holding the reactants and the products gets hot during the reaction. Use approximately 5 mL of 6M HCl and add to a testtube containing a small peice of mossy Zn. Immediately place a thermometer in the testtube and you will see a quick rise in temperature. This rise in temperature indicates that heat is given off which is a clear sign of an exothermic reaction. Hope this helps!!
Is reaction of potassium iodide and water exothermic or endothermic?
Its endothermic... In my experiment, it went from 26 to 25 degrees celsius... Its endothermic... In my experiment, it went from 26 to 25 degrees celsius... This is wrong it is exothermic. Potassium chloride is snow salt. it is used because not only does it react with the snow to create hydrochloric acide and potassium hydroxide (both with much lower freezing points) but, the EXOTHERMIC reaction also helps melt the snow No, it is endothermic. The only reason we add salt to snow is to lower the melting point. If you're curious, dissolve as much KCl in a beaker as you can as quickly as you can. The water temperature will drop dramatically.
What happens when Hydrochloric acid reacts with ammonium hydroxide is this a exotheermic or endothermic?
HCl + NH3 --> NH4Cl is already exothermic Ammonium hydroxide is the solution of NH3 in water, giving the following exothermic reaction: [NH4OH]aq + H+aq + Cl-aq --> NH4+aq + H2Oliq + Cl-aq
When hydrocholoric acid and sodium hydroxide react is it exothermic?
Yes, it is an exothermic reaction.
