When water vapor in the atmosphere loses heat and cools down, condensation happens. As the water vapor cools down and condenses, it attaches to small particles of dust floating in the atmosphere, forming tiny liquid water droplets.
NaOH +HCl ---> NaCl +H2O
n (mol HCl) = n (mol NaOH)
M- molarity
V - volume
M(HCl)V(HCl) = M(NaOH)V(NaOH)
M(HCl)= M(NaOH)V(NaOH)/V(HCl)
M(HCl)= 10⁻³*25.3 ml/5.25 ml=<span>4.82 × 10⁻³ M molarity HCl</span>
