What is a logical way that you could begin to investigate why your tire had low air pressure? Look to see if there is a hole in

the tire. Feel the tire for air escaping from it. Place the bike in a warm location to see if the tire pressure increases. Apply an outside pressure to the tire and listen for air escaping from the tire.

Assume the pH of household bleach is 12. What is the hydronium ion concentration in household bleach? What is it hydroxide ion c
Ostrovityanka [42]

Answer:

[H3O+] = 1.0*10^-12 M

[OH-] = 0.01 M

Explanation:

We can use the following equation to find the hydronium ion concentration.  Plug in the pH and solve for H3O+.

pH = -log[H3O+]

<u>[H3O+] = 1.0*10^-12 M</u>

Now, to find the hydroxide ion concentration we will use the two following equations.

14 = pH + pOH

pOH = -log[OH-]

14 = 12 + pOH

pOH = 2

2 = -log[OH-]

<u>[OH-] = 0.01 M</u>
