Try c I think is the most accurate one
The answer is: first substance is base and second is acid.
Bases, for example solution of sodium hydroxide (NaOH) feels slipery.
Sodium hydroxide dissociation in water: NaOH(aq) → Na⁺(aq) + OH⁻(aq).
Ionic compounds are good good electricity and heat conductors, because ionic compounds have mobile ions (cations and anions) that are able to transfer electrical charge.
In second reaction, magnesium is oxidized from oxidation number 0 to +2 and hydrogen is reduced from +1 to 0 (hydrogen gas).
Answer:
The answer to your question is pH = 9.08
Explanation:
Data
pH = ?
Concentration = 1.2 x 10⁻⁵ M
Process
1.- Calculate the pOH of the solution
Formula
pOH = -log[OH⁻]
pOH = -log[1.2 x 10⁻⁵]
pOH = 4.92
2.- Calculate the pH
Formula
pH = 14 - pOH
Substitution
pH = 14 - 4.92
Result
pH = 9.08
Answer:
