Step-by-step explanation:
Answer:
pOH = 9.4
Step-by-step explanation:
Mathematically;
pH + pOH = 14
pOH = 14 - pH
But pH = -log[H3O+]
From the question [H3O+] = 2.5 * 10^-5
Thus pH = -log (2.5 * 10^-5)
pH = 4.6
Thus;
pOH = 14-4.6
pOH = 9.4
Answer:
x=30
Step-by-step explanation:
Let's solve your equation step-by-step.
35=1.5x−10
Step 1: Flip the equation.
1.5x−10=35
Step 2: Add 10 to both sides.
1.5x−10+10=35+10
1.5x=45
Step 3: Divide both sides by 1.5.
1.5x÷1.5=45÷1.5
x=30
