Why zinc hydroxide is  soluble in NaOH ?

Look up the meaning of the word "amphoteric", because that is why zinc hydroxide dissolves in NaOH.

If Fe(OH)3 and NaOH get together they have no reason to combine. They are both hydroxides and sodium and iron are both metals. Although sodium hydroxide is a strong reagent, both metals want to give away electrons and there is no other reactant to give them to.

The answer will depend on th strength of the solution. At an equal concentration,  sodium hydroxide will have a much higher pH than an solution of sodium carbonate.\n\nA 10% solution of sodium carbonate will have a much higher pH than 0.00001 M solution of sodium hydroxide.

the other product is zinc chloride.\nand the reaction is single replacement.

yields "H2 + Zn2O3"\n\n^^!

na+2h2o=na(oh)2 + h2\n1.Note that na is a highly reactive metalk reacts even with cold water producing sodium hydroxide and liberating hydrogen.\n2h2so4+naoh = na(so4)2 +2h2o\nNote that h2so4 (sulphuric acid) reacts with naoh(sodium hydroxide),abase and the reaction b/w acid and base forming water and a salt is called neutralization reaction

i would assume it depends on the plastic.  But NaOH pellets are stored in HPDE (high density polyethylene) plastic containers.  So my thinking is if concentrated NaOH is stored in plastic than the liquid should also be able.

Sodium Hydroxide (aqueous). It's a solution in water of the compound NaOH.

Carefully. NaOH can be dangerous, just like any compound, in high enough concentrations.

The reaction between Hydrochloric acid and Sodium Hydroxide is as follows,\n\nHCl + NaOH --> NaCl + H2O\n\nYou can see that there is a 1:1 ration between the number of moles of HCl needed to completely reacted with NaOH.\n\nSince you are given both a volume and concentration of the NaOH solution, you should be easily able to calculate the number of moles of NaOH availible.\n# mole = volume * concentration\n# moles = .1 Liters * .25 moles/L = .025 moles of NaOH\n\nIf you know you have .025 moles of NaOH, you know you need .025 moles of HCl to react it completely.\n\nIf you know that you have a .15 mole/Liter solution of HCl, you can calculate the volume required to get .025 moles lie this,\nLiters = moles / oncentration\nLiters = .025 moles / .15 moles/Liter = .01667 Liters or about 167 mL of solution.\n\n\nNext time do your own homework.

Zinc chloride is soluble in water, but silicon dioxide is not. Therefore, their separation can be accomplished by using water.\n\nHope this helps,\nUltimeaciax

Zn is more reactive than Ni  (this is bcoz Zn is placed higher than Ni in the periodic table), so it would displace Ni from the solution of Ni(NO3)2. The reaction is \nZn + Ni(NO3)2 ----> Zn(NO3)2 + Ni

NaOH is lye. It's used in soap.\nBa(OH)2 is used to clean up toxic acid spills\nNH3 is ammonia, which is used in cleaning products\nMg(OH)2 is another base

For solubility.  Many drugs have carboxylic acid functionalities which are more soluble in water (i.e. blood, etc.) as their sodium salts

There is no sodium hydroxide. One mole of H2SO4 will react with 2 moles of NaOH in a neutralization reaction.

use sodium hydrolic solution

zinc is oxidised by almost all acids with varying degrees of rate.\n\nA+
