DIRECTIONS: Enter your answer as an ordered pair: (? , ?)
Dmitry [639]

Answer:

(0, 4 )

Step-by-step explanation:

To find the x- intercept, let y = 0 in the equation and solve for x, that is

7x - 4(0) = 28, that is

7x = 28 ( divide both sides by 7 )

x = 4 ← x- intercept ⇒ (0, 4 ) as an ordered pair

The pH of lemon juice at 298 K is found to be 2. 32. What is the concentration of mc014-1. Jpg ions in the solution? Use StartBr
sdas [7]

The concentration of ions in the solution of lemon juice whose pH value is 2.32 is 4.79×10⁻³ M.

<h3>What is pH value?</h3>

The pH value shows that how much a solution is acidic or basic. The range of the pH value lies between the 0-14.

The pH value can be calculated with the following formula.

\rm pH=log[H^{+}]

Here, [H⁺] is the molar hydrogen ion concentration.

The pH of lemon juice at 298 K is found to be 2. 32. Put this value of pH in the above formula as,

\rm 2.32=log[H^{+}]\\\ [H^{+}]=4.79\times10^{-3} \rm \; M

Hence, the concentration of ions in the solution of lemon juice whose pH value is 2.32 is 4.79×10⁻³ M.
