C number of particles dissolved
Answer:

Explanation:
1. Calculate the moles of NaOH.
2. Calculate the volume of NaOH

Answer:
pH of HNO₃ having an hydrogen ion concentration of 0.71M is 0.149
Explanation:
HNO₃ (aqueous) ⇄ H⁺ + NO3⁻
The pH is defined as the negative log of the hydrogen ion concentration
pH = - log [H⁺]
From the question, the hydrogen ion concentration is given as 0.71M, therefore
pH = -log [0.71]
= 0.149
17, to be neutral it has to have equal number of protons and electrons
It teacts with OH and makes water and salt
