She flipped to the data sheet. Ka1 of H₂SO₃ = 1.54 × 10�². Ka2 = 1.02 × 10��. Kb for HSO₃� = Kw/Ka1 = (1×10�¹�)/(1.54×10�²) = 6.49×10�¹³.

That night, she’d thrown her textbook across the room. It hit the wall with a satisfying thwack and fell open to Module 6: Acid/Base Reactions. Page 294. A diagram of a titration curve. The shape of a sigh. hsc chemistry 9 crack

Her father had knocked gently. "Mira? Everything okay?" She flipped to the data sheet

Mira put her head on the desk. The wood was cool. She could smell highlighter ink and her own exhausted sweat. Kb for HSO₃� = Kw/Ka1 = (1×10�¹�)/(1

It wasn’t a ghost. It was a mark. The decimal point was a cold spike in her chest, the zero a mocking mouth. Her first HSC Chemistry assessment task back. She had cracked —not the exam, but herself. Two hours of staring at equilibrium constants until they swam off the page like startled fish.
