Guess them using as few clues as possible


Chemistry ConundrumsOnline version guess the term by Merin Das 1 I start off clear, no color in sight, But add a base, and I turn pink—what a sight! In acid, I’m invisible, but that’s not all, I change when the pH rises, answering the call. What am I, who plays the role, Of telling you when acids lose control? What am I? 2 I’m the energy it takes to pull away, An electron from an atom in a single way. The more tightly bound, the higher my price, I increase as you go from left to right. I'm key to how atoms behave, So tell me now, what energy do you crave? 3 I dissolve in water, but not all the way, I only give up some protons, not the full display. In a solution, I stay partially unbound, Not as strong as others, I’m not the most profound. What am I, with a presence that's mild, A bit acidic, but not too wild? What am I? Hints 1 Acetic Acid, Citric Acid, Formic Acid 4 I have two protons that I love to share, One by one, in solutions, I’ll dare. In water, I dissociate with ease, But I don’t give all at once—only in twos, if you please. What am I, with a double gift to give, Hints 1 Sulphuric Acid is an example 5 I’m formed when one donates, the other just takes, A bond that’s unique, where no one forsakes. One atom gives both electrons, without a fight, While the other atom simply holds them tight. What am I, a bond with a special share, Where one gives more, but both still care? Hints 1 Ammonium Chloride has the bond 6 I’m not shared, but I’m still quite near, In an atom’s shell, I quietly appear. I stay by myself, not bonding at all, But when needed, I’ll answer the call. I help form bonds, though I’m not in the mix, What am I, with a pair that won’t fix? 7 I have two sides, with charges that differ, One’s slightly positive, the other’s a giver. I’m polar, not neutral, with a bit of a split, My ends have a charge, but they don’t always fit. What am I, with a tug on both ends, Hints 1 Water, HCl are examples 8 I’m made of oxygen, hydrogen too, With another element in the mix, just a few. When dissolved in water, I’ll give up my proton, A key in reactions, though I’m not the only one. What am I, with oxygen in my name, An acid by nature, but with oxygen's claim? 9 I form when opposites meet and bond so tight, One gives away, the other gains with might. Positive and negative, I hold them in place, Creating a structure, strong and in grace. In crystals I dwell, both hard and true, What force am I, keeping them glued? 10 I’m powerful and strong, a liquid so dense, In many reactions, I make no defense. Corrosive and sharp, I can burn through your skin, But dilute me a bit, and I’m harmless within. What am I?

Hints

Acetic Acid, Citric Acid, Formic Acid

I have two protons that I love to share, One by one, in solutions, I’ll dare. In water, I dissociate with ease, But I don’t give all at once—only in twos, if you please. What am I, with a double gift to give,

Hints

Sulphuric Acid is an example

I’m formed when one donates, the other just takes, A bond that’s unique, where no one forsakes. One atom gives both electrons, without a fight, While the other atom simply holds them tight. What am I, a bond with a special share, Where one gives more, but both still care?

Hints

Ammonium Chloride has the bond

I’m not shared, but I’m still quite near, In an atom’s shell, I quietly appear. I stay by myself, not bonding at all, But when needed, I’ll answer the call. I help form bonds, though I’m not in the mix, What am I, with a pair that won’t fix?

I have two sides, with charges that differ, One’s slightly positive, the other’s a giver. I’m polar, not neutral, with a bit of a split, My ends have a charge, but they don’t always fit. What am I, with a tug on both ends,

Hints

Water, HCl are examples

I’m made of oxygen, hydrogen too, With another element in the mix, just a few. When dissolved in water, I’ll give up my proton, A key in reactions, though I’m not the only one. What am I, with oxygen in my name, An acid by nature, but with oxygen's claim?
