Part B Calculate the specific heat (J/g °C) for a 25.0 g sample of a metal that absorbs 685 J when temperature increases from 33.4°C to96.8 °C.

Answer : The correct option is, It is basic and has a pH of 5.7.

Explanation :

As we are given the value of pOH is, 8.3

First we have to calculate the pH of the solution.

As we know that, the pH measures the acidity and basicity of the solution.

When the value of pH is less than 7 than the solution will be acidic.

When the value of pH is more than 7 than the solution will be basic.

When the value of pH is equal to 7 than the solution will be neutral.

As per question, the pH value is 8.3 that means the value of pH is greater than 7. Thus, the solution is basic in nature.

Hence, the correct option is, It is basic and has a pH of 5.7.
