Why is acid always added to water and not the reverse?

A lot of warmth is discharged when solid acids are blended in with water. Including increasingly corrosive discharges more warmth. On the off chance that you add water to corrosive, you structure an incredibly thought arrangement of corrosive at first. So much warmth is discharged that the arrangement may bubble viciously, sprinkling concentrated corrosive out of the compartment! In the event that you add corrosive to water, the arrangement that structures is weaken and the limited quantity of warmth discharged isn't sufficient to disintegrate and splash it. So Always Add Acid to water, and never the switch.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
