Question

The ph of the sample of hydrochloric acid used to tell whether the ph value of the change if the dilute it the water can it make the alkaline by adding the excessive of water

Answer 1

When an acidic solution is diluted with water the concentration of H + ions decreases and the pH of the solution increases towards 7. To make the pH change by 1, a tenfold dilution is required (eg adding 9 cm 3 of water to 1 cm 3 acid). The acid is becoming less acidic
