Chapter 23, Problem 1SAQ

Interpretation Introduction

Introduction: A metal that is found inside the earth in the form of mineral or ores is not in pure elemental state and metal is to be extracted from it.$$

Answer to Problem 1SAQ

Correct answer: Option $\left(a\right)$ is correct.

Explanation of Solution

Justify reason for correct statement:

Gold occurs in elemental state with some small particles and other substances. Hence, option $\left(a\right)$ is correct.

Justify reason for incorrect statements:

Other metals like titanium, chromium, and iron are found as either ores or minerals.

Titanium is found as oxides in ilmenite and rutile.

Iron is found as oxide in hematite.

Chromium is found as oxide in chromite.

Thus, these cannot be obtained in pure elemental state similar to that of gold.

Hence, options $\left(c\right)$, $\left(b\right)$, and $\left(d\right)$ are incorrect.

Conclusion

Gold is naturally found in elemental state.
