Answer :
The new pH will be 0.499.
The meaning of pH.
A way to gauge how basic or acidic a material or solution is. A pH of 7 indicates neutrality on this scale, which implies it is neither acidic nor basic. It is more acidic and basic if the pH value is less than or equal to 7, respectively.
There are two ways to measure pH: colorimetrically using indicator fluids or papers, or electrochemically, which is more precise and uses electrodes and a millivoltmeter (pH meter).
pH = -log (H₃⁺O)
Thus, it is possible to state that the solution's pH will be after diluting it.
[tex]pH_{dil}[/tex] = -log [tex](H^{+} _{{} 3} 0)_{dil}[/tex]
[tex]pH_{dil}[/tex] = -log [tex](H^{+} _{{} 3} 0)_{dil}[/tex]/2
[tex]pH_{dil}[/tex] = -log (H₃⁺O)₀ - log2
pH₀ = -log (H₃⁺O)₀
pH₀ = -log (1.58)
pH₀ = 0.198
[tex]pH_{dil}[/tex] = log2 +pH₀
[tex]pH_{dil}[/tex] = log2 +0.198
[tex]pH_{dil}[/tex] = 0.499.
