Solution B hasa Saoaum ion concentration of 2.5 x 10* M Which solution has the larger hydronium ion concentration? Which solution has the greater pH? te the pH of an aqueous solution of each of the following compounds by Indicating b. MgtOH) h. KC,H,O,_ L HCHO, d. HNO, NHog) . Which solution has the lower pH? a. 0.1 M HCl or 0.1 MHC2Hao, b. 0.1 M NaOH or 0.1 M NH c.0.1 M Na,CO, or 0.1 M NaCI -

Explanation / Answer

Ans 1 : Acidic property.

The chemical properties of the solutions are hugely contributed by its acidic character. The way it reacts with the other acids and bases , are solely determined by it. The pH of the solution helps to understand its acidity.

It refers to the negative logarithm of hydrogen ion concentration in the solution. Its range is 0 to 14 . Where the pH below 7 is acidic character , and above 7 is basic.
