Concept explainers
(a)
Interpretation:
Manganese(II) hydroxide and calcium iodate pair is given, the more soluble compound in water has to be identified.
Concept Introduction:
Solubility product constant:
The equilibrium constant of a more soluble ionic compound in water at the higher solubility is known as solubility product constant.
The equilibrium constant of more soluble ionic compound is given by
Ion product:
The multiplication of concentrations of ions which are raised to the power of number of respective ions present in the molecular formula. This gives the ion product.
Precipitation occurs when solution is supersaturated,
Precipitation will not occurs when solution is saturated and in equilibrium,
Precipitation will not occurs when solution is unsaturated,
(b)
Interpretation:
Strontium carbonate and cadmium sulfide pair is given, the more soluble compound in water has to be identified.

- Explain the term “inductively coupled plasma.”arrow_forwardUsing Pauling electronegativity values and a Ketelaar triangle, what type of compound is brass, a CuZn alloy? Group of answer choices metallic ionic covalentarrow_forwardChallenging samples: 1. Metal complexes with low volatility are often difficult to analyze when performing atomic absorption measurements because the atomization efficiency is reduced to unacceptably low levels. Devise a strategy or strategies for eliminating the problem of a non-volatile metal complex? Explain how you would do that. 2. Devise a strategy to overcome unwanted ionization of the analyte? Explain what it would be. 3. Devise a general method that can be used to account for the presence of unknown matrix effects.arrow_forward
