Find the pH of HCl with a concentration of 0.00006M<br> Round to the nearest whole number
Tpy6a [65]

Answer:

4.22

Explanation:

pH stands for potential hydrogen. The letter “p” denotes potential and the letter “H” denotes hydrogen.

pH helps to find the acidity or alkalinity of an aqueous solution.

The number of hydrogen ions (protons) present in a solution is determined by the pH scale.

A pH greater than 7 makes the water more alkaline and a pH less than 7 makes the water more acidic.

pH=-\log [H^+]=-\log [0.00006]=4.22

A student sees a change in mass in the lab when mixing two chemicals what is a possible explanation?
Hitman42 [59]

Answer:

The mixing of two chemicals may result in the production of a gas which is lost to the air. This will reduce the mass of the chemical mixture, because mass is being lost in a gaseous form.
