Question

Which of these has the highest h+ concentration? lemon juice, ph = 2.3 red wine, ph = 3.2 tomato juice, ph = 4.7 household ammonia, ph = 10.8?

Answer 1

Answer:

Lemon juice has the highest $H^+$ concentration.

Explanation:

The pH of the solution id the negative logarithm of hydrogen ion concentration in an aqueous solution.

$pH=-\log[H^+]$

1) Lemon juice with pH = 2.3

$2.3=-\log[H^+]$

$[H^+]=0.005011 M$

2)Wine with pH = 3.2

$3.2=-\log[H^+]$

$[H^+]=0.006309 M$

3)Tomato juice with pH = 4.7

$4.7=-\log[H^+]$

$[H^+]=1.99\times 10^{-5} M$

4)House hold ammonia  with pH = 10.8

$10.8=-\log[H^+]$

$[H^+]=1.584\times^{-11} M$

Answer 2

Lemon juice has the highest h+ concentration. The more acidic something is the more H+ it has.

ph = 1 is the most acidic
ph = 14 is the most basic (opposite of acidic... think of soap.)
