Strong hydrochloric acid can dissolve many substances. Which type of hazardous waste would this acid be?

Chemistry
1 answer:
KonstantinChe [14]3 years ago
4 0

Answer:

C. Corrosive waste

Explanation:

Hydrochloric acid is formed when hydrogen chloride gas is dissolved in water. The gas is toxic when inhaled and dissolves very readily in water to form the acid.

Hydrochloric acid is a strong acid as it ionizes completely in aqueous solutions to produce chloride ions and hydronium ions.

The concentrated acid is very corrosive in that it dissolves many other substances. Therefore, great care must be taken when handling the concentrated form of the acid.

It poses an environmental hazard due to its corrosive nature. Also, in industries and science laboratories, concentrated hydrochloric acid can corrode metal pipes and should not be drained into pipes without first being diluted.

However, the acid is very important in many industrial as well as laboratory procedures.

Which of the following statements is NOT true?
maria [59]

Answer : The incorrect statements are:

(A) When two nonmetals react, the compound formed is ionic.

(B) Two nonmetals can undergo an oxidation-reduction reaction.

Explanation :

Covalent compound : It is defined as the compound which is formed by the sharing of electrons between the atoms forming a compound.

The covalent compound are usually formed when two non-metals react.

The two nonmetals can not undergo an oxidation-reduction reaction.

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

Ionic compound are usually formed when a metal reacts with a non-metal.

The metal-nonmetal reaction can always be assumed to be an oxidation-reduction reaction.

For example : 2Na(s)+Cl_2(g)\rightarrow 2NaCl(s)

In this reaction, sodium shows oxidation because the oxidation state changes from (0) to (+1) and and chlorine shows reduction because the oxidation state changes from (0) to (-1).

Hence, the incorrect statements are, (A) and (B)

9. During an experiment the students prepared three mixtures A)Starch in water B) Sodium chloride solution C) Tincture of Iodine
il63 [147K]

Answer:

See explanation

Explanation:

Tyndall effect refers to the scattering of light in a solution. Tyndall effect occurs when the size of particles in the solution exceeds 1 nm in diameter. Such solutions are actually called false solutions.

In tincture of iodine, the size of particles in solution is less than 1 nm in diameter hence the solution does not exhibit Tyndall effect. Hence, tincture of iodine is a true solution.

Therefore, if the size of particles in solution exceeded 1nm in diameter, Tyndall effect is observed.

Bromophenol blue is the indicator used in detecting the endpoint for the antacid analysis in this experiment. what is the expect
Paul [167]
Hello!

For the antacid analysis, the chemical reactions that occur in the titration are the following ones:

First, the antacid (composed of weak bases and carbonates) is completely neutralized by the H⁺ ions in the HCl

2HCl + CaCO₃ → CO₂ + H₂O + 2CaCl₂

HCl + OH⁻ → H₂O + Cl⁻

The titration reaction consists in titrating the excess H⁺ ions that are left in the solution, by the following reaction:

H⁺ + NaOH → H₂O + Na⁺

So, when the equivalence point is reached, the solution will go from acid to basic. As bromophenol blue is yellow in acidic solution and blue in basic solution, you'll expect the indicator to change from yellow to blue.

Have a nice day!
