Answer:
12.1; acidic
Explanation:
I'm assuming the hydrogen concentration is H+.
So, first we must find pH.
pH = -log[H+]
I simply just plugged in the concentration.
I get 1.9 as the pH. This means that the substance is very acidic since it has a low pH.
Now to find poH.
poH + pH = 14
I simply plugged in once again!
I get 12.1 as the poH. This also determines that the substance is very acidic since it has a high poH.
Common household substances that are acidic include coffee, battery acid, vinegar and lemon juice, while common household substances that are basic include drain cleaner, bleach, soap, ammonia, milk of magnesia and baking soda.An acid is a substance that has a pH value of less than seven, while a base is a substance that has a pH value of greater than seven.
I belive this should help :)
- A car travels 120km due to North .
- At last the car reached on town B from town A .
- The car's total displacement from town A to B .
✍️ See the attachment diagram .
✯ Hence, Total displacement from town A to town B is “ <u>8</u><u>2</u><u>k</u><u>m</u> ” .
