Calculate the ph of a buffer that is 0.145 m hc2h3o2 and 0.202 m kc2h3o2. The ka for hc2h3o2 is 1.8 × 10-5.
koban [17]

Answer:

pH = 4.8

Explanation:

A buffer is formed by a weak acid (0.145 M HC₂H₃O₂) and its conjugate base (0.202 M C₂H₃O₂⁻ coming from 0.202 M KC₂H₃O₂). The pH of a buffer system can be calculated using Henderson-Hasselbalch's equation.

pH = pKa + log\frac{[base]}{[acid]} \\pH = -log(1.8 \times 10^{-5} )+log(\frac{0.202M}{0.145M} )\\pH=4.8

6. Explain the impact on fresh water of:
Paraphin [41]

Fresh water pollutants  are substances which pollute fresh water and  industrial waste, is most harmful fresh water pollutant to man and aquatic organisms.

<h3>What are pollutants?</h3>

Pollutants are substances which cause harm when they are present in the environment.

Pollutants include chemicals such as petroleum and material such as sewage.

The presence of pollutants in freshwater results in water pollution and make the water unfit for drinking purposes and also harms aquatic life in freshwaters.

Some freshwater pollutants include:

  • Farming wastes
  • Household pollutants
  • Industrial wastes
  • Erosion
  • Oil and Gasoline
  • heat

Of these pollutants, the most dangerous fresh water pollutant is industrial wastes as they kill aquatic organisms most due to the presence of harmful chemicals in them.

Therefore, fresh water pollutants such as industrial waste is most harmful to man and aquatic organisms.
