Equal pieces of zinc granules are dropped in four test tubes. Following substances are poured in all the four test tubes. The reaction will be vigorous with
CH3COOH
HCl
sodium bicarbonate solution
lemon juice.

Academic Chemistry NCERT Class 10

Correct Answer: (b) HCl
Explanation: Strong adds like HCl react vigorously with active metals like Zn form metal salt and evolve H₂ gas.
$Zn(s) + HCl(aq) \rightarrow ZnCl_2(aq) + H_2$

Equal lengths of magnesium ribbons are taken in test tubes A and B. Hydrochloric acid (HCL) is added to test tube A, while acetic acid (CH3COOH) is added to test tube B. Amount and concentration taken for both the acids are same. In which test tube will the fizzing occur more vigorously and why?

A student added few pieces of aluminium metal to two test tubes A and B containing aqueous solutions of iron sulphate and copper sulphate. In the second part of her experiment, she added iron metal to another test tubes C and D containing aqueous solutions of aluminium sulphate and copper sulphate.In which test tube or test tubes will she observe colour change? On the basis of this experiment, state which one is the most reactive metal and why.

A student takes Cu, Al, Fe and Zn pieces separately in four test tubes labelled as I, II, III, and IV respectively. He adds 10 mL of freshly prepared ferrous sulphate solution to each test tube and observes the colour of the metal residue in each case.He would observe a black residue in the test tubes :(1) (I) and (II) (2) (I) and (III) (3) (II) and (III)(4) (II) and (IV)"

In three test tubes A, B and C, three different liquids namely, distilled water, underground water and distilled water in which a pinch of calcium sulphate is dissolved, respectively are taken. An equal amount of soap solution is added to each test tube and the contents are shaken. In which test tube will the length of the foam (lather) be longest? Justify your answer.

A student takes about 4 ml of distilled water in four test tubes marked P, Q, R and S. He then dissolves in each test tube an equal amount of one salt in one test tube, namely sodium sulphate in P, potassium sulphate in Q, calcium sulphate in R and magnesium sulphate in S. After that he adds an equal amount of soap solution in each test tube. On shaking each of these test tubes well, he observes a good amount of lather (foam) in the test tube marked.(A) P and Q (B) Q and R (C) P, Q and S (D) P, R and S

Candidates of four schools appear in a mathematics test. The data were as follows:

2 mL each of conc. HCl, cone. HNO3 and a mixture of conc. HCl and conc. HNO3 in the ratio of 3: 1 were taken in test tubes labelled as A, B, and C. A small piece of metal was put in each test tube. No change occurred in test tubes A But the metal got dissolved in test tube C. The metal could be.AlAu CuPt.

2 mL each of concentrated HCl, HNO3 and a mixture of concentrated HCl and concentrated HNO3 in the ratio of 3: 1 were taken in test tubes labelled as A, B and C. A small piece of metal was put in each test tube. No change occurred in test tubes A and B but the metal got dissolved in test tube C respectively. The metal could beAlAuCuPt
