pH = - log [H+], Given concentration is 2.0 M
pH = - log 2
pH = - 0.3010.
Hence option 'd' is correct.
please answer all question show work number 7 only please The pH of 2.0M HCI is a) 2.0, b) 1.0, c) 0.0, d)<0.0. 1. 2. Thymol blue appears red below pH 1.0, yellow between pH 2.5-8.0, and blue above pH 9.5. An aqueous solution turns green upon adding one drop of thymol blue. The pH of this solution is a) 0.5, b) 7, c) 9, d) 11. The buffer HF/F can' be prepared by mixing a) HF and NaF, b)...

A 1.0 nC charge is placed at (0.0 cm, 2.0 cm) and another 1.0 nC charge is placed at (0 cm,-2.0 cm). A third charge +q is placed along a line halfway between q1 and q2 such that the angle between the forces on q due to each of the other two charges is 60∘. The resultant force on q is (5.0 × 10^-5i) N. What is the magnitude of the charge q?
