<u> Increasing pH will </u><u>increase </u><u>solubility of the </u><u>PbI2</u>

What is equilibrium reaction ?

In a chemical reaction, chemical equilibrium is the state in which both the reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.

PbI2 + 2OH- (aq)  ----> Pb(OH)2(s) + 2I- (aq)

Pb(OH)2 is insoluble therefore increasing pH will lead to the formation of the more solid lead (ll)hydroxide which will help to solubulate more PbI2

therefore equilibrium will shift to right side means increasing pH will increase solubility of the PbI2.

Guys i need help <br> What is the chemical equation for foam fight
Radda [10]

Answer:

Hydrogen Peroxide

Explanation: Hydrogen peroxide breaks down into oxygen and water. As a small amount of hydrogen peroxide generates a large volume of oxygen, the oxygen quickly pushes out of the container. The soapy water traps the oxygen, creating bubbles, and turns into foam.

How long would it take a current of 10A to deposit 6.36g of copper during the electrolysis of copper (ll) tetraoxosulphate VI so
zhuklara [117]

It take 0.54 hours to deposit 6.36g of copper

<h3>Further explanation</h3>

Faraday's Law I

"The mass of the substance formed at each electrode is proportional to the electric current flowing in the electrolysis

W = e.i.t / 96500

\tt \large {\boxed {\bold {W \: = \: \dfrac {e \times  i \: x \: t} {96500}}}}

e = equivalent = Ar / valence

i = current, A

t = time, s

W=6.36 g

e = 63.5 : 2 =31.75

i = 10 A

\tt t=\dfrac{W\times 96500}{e.i}\\\\t=\dfrac{6.36\times 96500}{31.75\times 10 }\\\\t=1933.04~s\approx 0.54~hours
