Calculate the concentration of h3o+ in a solution that contains 5.5 × 10-5 m oh- at 25°c. identify the solution as acidic, basic, or neutral.
a. 1.8 × 10-10 m, acidic
b. 9.2 × 10-1 m, basic
c. 5.5 × 10-10 m, neutral
d. 9.2 × 10-1 m, acidic
e. 1.8 × 10-10 m, basic

The correct answer is option (e).

Explanation:

Concentration of hydroxide ions

The pOH of the solution is defined as negative logarithm of hydroxide ions of in an aqueous solution.

pH +pOH = 14

pH = 14-pOH

pH=14 - 4.259 = 9.741

The pH of the solution is defined as negative logarithm of hydronium ions of in an aqueous solution.

The solution is basic as pH of the solution is 9.741.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
