Witrynaa) In the case of the apple juice, the hydrogen ion concentration is [H+] = 0.0003, so: pH = −log [H+] = −log [0.0003] = 3.52287874528... This value is less than 7, so the apple juice is acidic. b) In the case of the ammonia, the hydrogen ion concentration is [H+] = 1.3 × 10−9, so: pH = −log [H+] = −log [1.3 × 10−9] = 8.88605664769...

Witryna25 maj 2024 · For those of us who grew up in the digital age and so have memorized the table of powers of 2 to many exponents (I know them to exponent 16 off top of my head), this is easy using logarithms base 2: 128 ∗ 512 = 2 7 ∗ 2 9 = 2 16 = 65536. Notice: this is nothing more nor less than a logarithm calculation. Witryna18 lut 2016 · For example: If = 10–2 M, then = 10–12 Thus, the product = (10–2 × 10–12) = 10–14 M If = 10–10 M, then = 10–4 Thus, the product = (10–10 × 10–4) = 10–14 M We can say that the nature of the solution (Acidic, Basic or Neutral) can be found by hydrogen ions concentration or hydroxyl ions concentration . bobby\u0027s old fashioned barber shop https://dogflag.net
