What is the ph of 0.001mh2so4

Answer 1

$\underline{\sf{\purple{\mapsto\mathscr{C}orrect\: \mathscr{Q}uestion}}}$.

What is the ph of 0.001M of $\sf H_2SO_4$.

$\underline{\sf{\purple{\mapsto\mathscr{A}nswer:}}}$.

Molarity of $\sf H_2SO_4$ = 0.001 M

We know that pH is ,

$\boxed{\red{\bf\dag pH=-log_{10} [H^+]}}$

=> pH = - log [ H + ]

=> pH = - log [ 0.001 ]

=> pH = - log [ 1 / 1000 ]

=> pH = - log [ 10-³ ]

=> pH = -3 × -1 log 10.

=> pH = -3 × -1 × 1.

=> pH = 3 .

$\red{\bf Hence\: the\:pH\:is\:3.}$

★ pH :-

➳ It stands for potenz Hydrogen.

➳ It is calculated by negative logarithm of concentration of H + ions to the base 10.

➳ It is used to specify acidity or basicity of a substance .

➳ acids have pH value less than 7 while bases pH value more than 7.

➳ Neutral substances have PH value 7.
