We know that the pH of neutral solutions is 7, for acidic solutions is less than seven and for basic solutions is greater than 7.
pH = -log[H+]
pH = -log ( 1 x 10⁻⁴)
pH = 4
The answer is:
A) Acidic
1.2(1.79) = 2.1
Significant Figure = 2
Decimals = 1
Scientific Notation = 2.1(10)^0
So, 1.2(1.79) = 2.148
Round = 2.148
= 2.1
Sig Figs = 2
Answer is 2.1, or 2.1e + o
