A solution with a hydroxide ion concentration of 4.15 × 10-4 m is ________ and has a hydrogen ion concentration of ________. a solution with a hydroxide ion concentration of 4.15 × 10-4 m is ________ and has a hydrogen ion concentration of ________. basic, 2.41 × 10-10 m acidic, 2.41 × 10-10 m acidic, 2.41 × 10-11 m basic, 2.41 × 10-11 m

Respuesta :

solution with hydroxide ion concentration 4.15 x 10⁻⁴ M, has a pOH value of ;
pOH = -log (4.15x10⁻⁴)
pOH = 3.38
pH + pOH = 14
Therefore pH = 14 - 3.38 = 10.62
when pH> 7 the solution is basic .
since pH is known we can calculate hydrogen ion concentration 
[H⁺]= antilog (-10.62)
[H⁺] = 2.4 x 10⁻¹¹ M
answer is basic, 2.41 × 10-11 m

2.41 × 10-11 m

The concentration of hydroxide ion can be expressed in terms of pOH, which is close to (14 − pH), so the pOH of pure water is also close to 7.

What has more hydroxide ions than hydrogen ions?

  • Sometimes water collides with another water molecule are enough to force to transfer of hydrogen.
  • The result is a hydroxide ion (OH-) which is a base and a hydronium ion (H3O+), which is an acid.
  • This is known as self-ionization of water

Solution with hydroxide ion concentration 4.15 x 10⁻⁴ M, has a pOH value of ;

pOH = -log (4.15x10⁻⁴)

pOH = 3.38

pH + pOH = 14

Therefore pH = 14 - 3.38 = 10.62

when pH> 7 the solution is basic .

since pH is known we can calculate hydrogen ion concentration

[H⁺]= antilog (-10.62)

[H⁺] = 2.4 x 10⁻¹¹ M

answer is, 2.41 × 10-11 m
