Answer:
The pH os the substance is 1,92.
Explanation:
The pH is a measure that gives us an idea of the acidity or alkalinity of a solution. It is calculated as:
pH = -log (H +)= -log (1.2 x 10^-2 )=1,92
The pH scale ranges from values of 0 to 14 (less than 7.0 is acidic and greater than 7.0 is basic, a pH = 7.0 is neutral). In this case, the substance is acidic.
Yes, It is important to know the volume of Unknown acid or base to be titrated.
Titration is carried out in order to find out the concentration (i.e. molarity) of unknown acid or base. In this process a standard solution of acid or base is taken and is titrated with known volume of of titrant. At end point (neutralization) the amount of standard titrant utilized is calculated and following formula is employed to calculate the unknown concentration of unknown solution.
M₁V₁/n₁ = M₂V₂/n₂
Answer:
A. Mg(OH)2
Explanation:
all oxides are insoluble except those of Group IA metals. most sulfides S2- are insoluble, with the exceptions of Group I, II (slightly soluble) metals and ammonium - NH4+
