Question

calculator the ph of 0.0001 m hcl​

Answer 1

Answer:

4

Explanation:

there is 1 mol of H+ ions in 1 mol of HCl  

so 0.0001M HCl means there is 0.0001M H+ ions in there  

[H+] = 0.0001 M  

now you need a calculator  

the main formula is (assuming log base 10 on the calculator)  

pH = - log [H+]  

= - log [0.0001]  

= 4

hope this will help u

have a great day
