Back (Answer)

Key Elements Oxygen atoms (add water) Hydrogen atoms (add H⁺) Electrons States

#3
Front (Question)

Describe redox reactions in basic conditions

Back (Answer)

• solution with a greater concentration of hydroxide ions than hydrogen ions

#4
Front (Question)

KOHOHES - basic conditions

Back (Answer)

Key elements Oxygen atoms (add H₂O) Hydrogen atoms (add H⁺) OH - add OH⁻ ions to both sides of the equation for every H⁺ Electrons States

#5
Front (Question)

What is the formula for pH?

Back (Answer)

pH = -log₁₀[H⁺]

#6
Front (Question)

Describe pH changes in an acidic electrolyte:

Back (Answer)

• if H⁺ produced, pH decreases (more acidic) • if H⁺ consumed, pH increases (less acidic)

#7
Front (Question)

Describe the pH changes in a basic electrolyte:

Back (Answer)

• if OH⁻ produced, pH increases (more basic) • if OH⁻ consumed, pH decreases (more acidic)
