Gold and platinum will no react with HNO3 due to their low reactivity. Aluminum also will not react with HNO3 despite its relatively high reactivity because it has a protective layer of aluminum oxide on it.

What is the reaction of ZnSO4 and Cu?

CuSO4+Zn results in Cu+ZnSO4, but the reaction doesn`t take place the other way around CuSO4+Zn results in Cu+ZnSO4, but the reaction doesn`t take place the other way around CuSO4+Zn results in Cu+ZnSO4, but the reaction doesn`t take place the other way around


How acetone is converted into t-butyl alcohol?

Acetone can be converted to t-butyl alcohol using a Grignard reaction. First, react acetone with magnesium metal to form a Grignard reagent. Then, the Grignard reagent reacts with isobutylene (2-methylpropene) to yield t-butyl alcohol. This process involves multiple steps and careful control of reaction conditions to ensure a successful conversion.


What is the meaning of T in Eriochrome Black - T?

The "T" in Eriochrome Black T stands for the word "Tetrasodium," indicating that this compound contains four sodium atoms in its structure. Eriochrome Black T is a complexometric indicator commonly used in analytical chemistry for the determination of metal ions.


The temperature of a piece of unknown metal with a mass of 18.0 g increases from 25.0 degrees C to 40 degrees C when the metal absorbs 124.2 J of heat What is the specific heat of the unknown metal?

Without stating units, it is impossible to answer this question accurately. However, the equation you would need is q=mc∆T, where q is the heat flow (the 53.0 listed, likely Joules), m is the mass of the unknown metal (11.1, likely grams), c is the specific heat of the metal (the unknown you need to solve for), and ∆T is the change in temperature of the metal (24.1-13.0, likely Celcius). Rearranged to solve for specific heat, the question is c=q/m∆T.


Why you use eriochrome black T indicator in EDTA titration?

Eriochrome black T is used as an indicator in EDTA titrations because it forms a stable complex with the metal ions being titrated. It changes color at the endpoint of the titration, which helps in detecting when all the metal ions have been chelated by the EDTA. This color change signifies the completion of the reaction and allows for accurate determination of the metal ion concentration.
