Write the chemical equation for the reaction of lithium hydroxide (LiOH) with an Arrhenius acid of your choosing. Name and write

Inessa05 [86]

<h3>Answer:</h3>

LiOH(aq) +HCl(aq)→ LiCl(aq) + H₂O(l)

Salt formed is LiCl

<h3>Explanation:</h3>

Arrhenius acid refers to a substance that ionizes in water to generate protons or hydrogen ions.
Examples of Arrhenius acid include acids such as HCl, H₂SO₄ and HNO₃.
A reaction between Lithium hydroxide and an Arrhenius acid such as HCl will yield a salt and water.

That is;

LiOH(aq) +HCl(aq)→ LiCl(aq) + H₂O(l)

The salt formed is LiCl
The reaction is an example of neutralization reaction.

What reaction might we use to synthesize nickel sulfate,niso4? Write equations for acid base neutralization. Include states in y

il63 [147K]

Answer:

Here's what I get

Explanation:

1. Nickel sulfate

base + acid ⟶ salt + water

NiSO₄ is a salt of the base Ni(OH)₂ and the acid sulfuric acid.

Hydroxides of transition metals are insoluble; most sulfates are soluble.

$\underbrace{\hbox{Ni(OH)$_{2}$(s)}}_{\hbox{base}} + \underbrace{\hbox{H$_{2}$SO$_{4}$(aq)}}_{\hbox{acid}} \longrightarrow \, \underbrace{\hbox{NiSO$_{4}$(aq)}}_{\hbox{salt}} + \underbrace{\hbox{2H$_{2}$O(l)}}_{\hbox{water}}$
